class="search-article-abstract" keep_len="250"><p>This paper presents various aspects of atmospheric refraction to gain insight into the advances in this field. It divides the effects of atmospheric refraction into two categories: the visible-to-infrared bands used in research fields such as optical imaging, laser transmission, and optoelectronic tracking and the radio band used in radar measurements and satellite detection. The calculation formulas for these two bands are different in their practical treatment. This paper introduces the refractive index formulas according to the refractive index formula's development history and points out the limitations of each formula. The current best choice for the former formula is the one summarized by Rüeger scholars; for the latter, it is recommended to choose the radio refractive index formula in the Rec. ITU-R P.453-14. In addition, the relationship between the refractive index of the Earth's surface and altitude, reference data for the refractive index on a global scale, and statistical distributions for the calculation of the refractive index gradient are given in the recommendation. Finally, traditional calculation methods for obtaining atmospheric refraction and optical observation methods are presented. The former study is based on the modeling of atmospheric patterns or meteorological data, formulae for refractive indices in specific regions, or model fitting to satisfy accuracy in a single environment or on an average scale. The optical measurement method does not need an atmospheric model as a basis, nor does it rely on meteorological parameters. The measurement results of the data are real-time and more representative of the path.

By reducing the aberration of each component, the system tolerance sensitivity is reduced. The system achieves a 30× zoom ratio and continuous zoom with a long focal length of 30-900 mm. The system has advantages such as a large zoom ratio, long focal length zoom, extremely short total length, low sensitivity, and good image quality within the entire focal length range.

The static nonlinear part and dynamic linear part of the Hammerstein model are represented by models obtained through the Prandtl-Ishlinskii (P-I) model and Hankel matrix system identification method, respectively. This model demonstrates good generalization capability for typical input frequencies below 200 Hz. A sliding mode inverse compensation tracking control strategy based on P-I inverse model and integral augmentation is proposed. Experimental results show that compared with PID inverse compensation control and sliding mode control without inverse compensation, the sliding mode inverse compensation control has a more ideal step response and no overshoot, moreover, the settling time is only 6.2 ms. In the frequency domain, the system closed-loop tracking bandwidth reaches 119.9 Hz, and the disturbance rejection bandwidth reaches 86.2 Hz.

Therefore, we propose a method for optimizing the structural parameters of the electrowetting triple-liquid lens based on joint simulation. To design a triple-liquid lens, Comsol and Zemax software are used to establish triple-liquid lens simulation models under different structural parameters, and its focal lengths under different voltages are obtained. The effects of height and taper on zoom range and initial focal length are analyzed, and a set of structural parameters with the maximum zoom range and the longest initial focal length is determined. To verify the method’s reliability, we prepare the triple-liquid lens models with different heights and tapers, and conduct zoom experiments. The simulation and experimental results show that the initial focal length of the triple-liquid lens correlates positively with height and taper; the zoom range correlates positively with taper, but height is the main influencing factor. When the height is 12 mm and the taper is 20°, the lens has the most extensive zoom range and the longest initial focal length. When the taper is less than 15°, the simulation and experimental results are highly consistent.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="efb56fcf-55f5-4039-9d33-b84785547f28" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0119-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0119-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0119-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0119" class="" target="_blank">Research progress in the phenomenon of exceptional point on passive non-Hermitian metasurfaces</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","ZHUO Yi-zhou","");'>ZHUO Yi-zhou</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WEI Zhong-chao","");'> WEI Zhong-chao</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0119" target="_blank" class="mainColor">10.37188/CO.2024-0119</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0119" target="_blank" class="mainColor">32171.14.CO.2024-0119</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0119" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">134</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0119" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">65</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('efb56fcf-55f5-4039-9d33-b84785547f28');"><img src="/style/web/images/custom/icopdf.png" />PDF 3781KB</a>(<span class="colorRed pdf-num">25</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In non-Hermitian systems, controlling the gain or loss of the system can enable the system state transition from PT-symmetry to broken PT-symmetry. This transition leads to a special point known as the exceptional point, where the system eigenvalues and eigenstates become simultaneously degenerate. When combined with metasurfaces, the exceptional point leads to various intriguing optical phenomena, such as asymmetric transmission, exceptional topological phase, and the non-Hermitian skinning effect. However, active metasurfaces introducing gains are difficult to realize experimentally. Therefore, designing passive metasurfaces using equivalent gains through loss becomes a powerful tool in non-Hermitian research. In this paper, we review the theoretical models, research progress, specific applications, and experimental design in the study of the exceptional point on passive non-Hermitian metasurfaces and look forward to the future direction of this field.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="b21dbd4f-d1ec-4575-a18e-ce9b286b2027" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0118-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0118-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0118-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0118" class="" target="_blank">Improved AO optimization algorithm for distortion parameter estimation of catadioptric omnidirectional lens</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","ZHANG Yue","");'>ZHANG Yue</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Ning","");'> ZHANG Ning</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XU Xi-ping","");'> XU Xi-ping</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0118" target="_blank" class="mainColor">10.37188/CO.2024-0118</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0118" target="_blank" class="mainColor">32171.14.CO.2024-0118</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0118" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">134</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0118" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">64</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('b21dbd4f-d1ec-4575-a18e-ce9b286b2027');"><img src="/style/web/images/custom/icopdf.png" />PDF 9512KB</a>(<span class="colorRed pdf-num">14</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Aiming at the problems of low accuracy and easy to fall into local optimal solutions of the existing lens distortion parameter estimation methods, a catadioptric omnidirectional camera lens distortion parameter method based on the improved Aquila Optimization (AO) algorithm is proposed. Firstly, the optimization ability of the AO algorithm is enhanced by integrating chaotic mapping, adaptive adjustment strategy, and population optimization strategy, which solves the problems of slow convergence speed and proneness to falling into local optimal solutions. Secondly, the distribution range of distortion parameters is derived and determined by the corresponding distortion edges of straight lines in the space and the single parameter division model. Then, the optimization objective function containing the distortion parameters is constructed. Finally, the improved AO algorithm is used to find the best distortion parameters for the optimization objective function. After analyzing the correction results of standard gallery images and omnidirectional images, the method proposed in this paper estimates the main point error within 0.5 pixels and the radial aberration coefficient error within 2.5%. It can effectively estimate the lens aberration parameters and realize the omnidirectional image aberration correction. It improves the visual navigation system's image quality under the task of environment perception and is valuable in engineering applications.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="c4315f32-67dd-4b36-bd42-e4a7cf563b37" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0085-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0085-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0085-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0085" class="" target="_blank">Improved integral sliding mode control strategy for the segmented are permanent magnet synchronous motor based on dual observer</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","CAO Zhao-jin","");'>CAO Zhao-jin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SONG Xiao-li","");'> SONG Xiao-li</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," FAN Ren-Qiu","");'> FAN Ren-Qiu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Chao","");'> ZHANG Chao</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0085" target="_blank" class="mainColor">10.37188/CO.2024-0085</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0085" target="_blank" class="mainColor">32171.14.CO.2024-0085</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0085" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">127</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0085" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">104</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('c4315f32-67dd-4b36-bd42-e4a7cf563b37');"><img src="/style/web/images/custom/icopdf.png" />PDF 3550KB</a>(<span class="colorRed pdf-num">12</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>With its high torque ratio and stable low-speed operation, the Segmented Arc Permanent Magnet Synchronous Motor (SAPMSM) provides high-performance drive technology support for large-aperture astronomical telescope observations. Improving the motor’s performance is challenging due to various internal and external interferences during its operation, such as parameter distortion, harmonics, etc. To this end, this paper proposes an integral sliding mode controller based on a new reaching law and a hybrid control strategy that combines an expanded state observer and a load observer, aiming to optimize the traditional sliding mode control and enhance the system’s anti-interference ability. The traditional reaching law has complicated parameters and cannot suppress chattering well. The new reaching law simplifies the parameters and effectively overcomes the system chattering. Second, an expanded state observer is used to estimate the feedback speed. Then, the q-axis current information and the estimated precise speed data are combined as the input of the load torque observer. This further improves the load observation performance and converts the load observation value into current for pre-processing. Feedback compensation is used to improve the motor’s anti-interference performance. Simulation and experimental results show that the proposed dual observer method can accurately observe the motor's speed and load, significantly enhancing the motor’s ability to resist load disturbances. At the same time, the new sliding mode speed controller reduces the motor speed overshoot and suppresses the buffeting of the sliding mode to a certain extent, providing theoretical and experimental support for arc motors in high-precision observation applications of large-aperture astronomical telescopes.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="e891c132-d0d2-4f9b-90a3-7784e206feeb" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0097-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0097-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0097-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0097" class="" target="_blank">Research on pointing accuracy of liquid crystal phase array based on the variable period grating method</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","CAO Zong-xin","");'>CAO Zong-xin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," QIAN Yi-long","");'> QIAN Yi-long</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Yu-tong","");'> LIU Yu-tong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Kun","");'> LI Kun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Zi-fan","");'> LI Zi-fan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," GONG Jun-hao","");'> GONG Jun-hao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," HU Wu-sheng","");'> HU Wu-sheng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Da-wei","");'> ZHANG Da-wei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," HONG Rui-jin","");'> HONG Rui-jin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," MAO Hong-min","");'> MAO Hong-min</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LU Huan-jun","");'> LU Huan-jun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," FAN Li-na","");'> FAN Li-na</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CAO Zhao-liang","");'> CAO Zhao-liang</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0097" target="_blank" class="mainColor">10.37188/CO.2024-0097</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0097" target="_blank" class="mainColor">32171.14.CO.2024-0097</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0097" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">132</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0097" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">72</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('e891c132-d0d2-4f9b-90a3-7784e206feeb');"><img src="/style/web/images/custom/icopdf.png" />PDF 2551KB</a>(<span class="colorRed pdf-num">24</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Liquid crystal optical phased array (LC OPA) is widely used in lidar, laser communication and laser weapons to scan and control laser beams.

In order to reconstruct the measured surface completely and accurately, a multiple exposure method is proposed in this paper. The proposed method can predict the exposure time according to the reflective intensity of the measured surface. Firstly, the camera response curve of the imaging system is obtained by projecting a series of uniform gray images at different exposure times, and the irradiance image that can reflect the reflection intensity of the measured surface is calculated. Then, the fuzzy C-means clustering method is used to adaptively segment different irradiance regions of the target and obtain the central irradiance of each region. The optimal exposure time is predicted for different reflection regions based on the camera response curve. Finally, the 3D reconstruction of the highly reflective surface is realized by combining the multiple exposure fusion algorithm. The experimental results show that the proposed method can simultaneously reconstruct the strongly reflective area and the excessively dark area of the aluminum alloy surface, with a reconstruction error of less than 0.5 mm, the maximum deviation reduced by 74.78%, and the standard deviation reduced by 48.96%. The proposed method can correctly predict the exposure time according to regional reflection characteristics, effectively overcome the problems of phase loss and phase distortion caused by regional overexposure and regional darkness, and completely and accurately reconstruct different reflection regions of highly reflective surfaces.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="ad4d22a0-a45e-4028-b7d0-30eaba99d447" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0108-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0108-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0108-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0108" class="" target="_blank">United calibration method for ship-borne radiation measuring system based on ambient temperature self-adaptive correction</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","SUN Xiao-dong","");'>SUN Xiao-dong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHEN De-ming","");'> CHEN De-ming</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YANG Guo-qing","");'> YANG Guo-qing</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SU Yan","");'> SU Yan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Li-jian","");'> ZHAO Li-jian</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0108" target="_blank" class="mainColor">10.37188/CO.2024-0108</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0108" target="_blank" class="mainColor">32171.14.CO.2024-0108</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0108" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">71</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0108" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">39</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('ad4d22a0-a45e-4028-b7d0-30eaba99d447');"><img src="/style/web/images/custom/icopdf.png" />PDF 3821KB</a>(<span class="colorRed pdf-num">5</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>As an important component for the information database, infrared data has been extensive used in night vision, weapon guidance, long-range early warning systems and more. Shipborne infrared radiation characteristic measuring systems work in the marine environment, where the variation in temperature and humidity is vast. In view of the fact that variation in ambient temperature greatly affects while improving the measuring system, this paper presents an internal and external united calibration method based on ambient temperature self-adaptive correction. It ccorrects temperature influence through self-adaptive interpolation, thus confirming the validity of the proposed measuring system for sensibility and responsive characteristics of external targets. Radiant calibration in different infrared wavebands has been completed by the measuring system, serial temperatures have been set in each integrating time to calibrate and fit, and the method's effectiveness has been determined by error statistics. Meanwhile, the radiation characteristics of high-precision blackbody and aquatic targets are inversed. As a result, the minimum and the maximum error's obtained for blackbody measuring precision were 6.82% and 10.21%, respectively. The high confidence coefficient for measured radiant inversion value verifies the effectiveness and application prospects of the calibration method presented in this paper.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="2879a34f-cb0b-473e-9465-267d781d58e6" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/img/cover/dd1838c5-f4dc-4614-ad0e-0aae1fc106ee.jpg"> <img src="/fileZGGX/journal/img/cover/dd1838c5-f4dc-4614-ad0e-0aae1fc106ee.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/img/cover/dd1838c5-f4dc-4614-ad0e-0aae1fc106ee.jpg'" class="figure_img" id="Fig-11" ref="#Fig-11"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN.2024-0034" class="" target="_blank">Design Optimization of a Sensitivity-Enhanced Tilt Sensor Based on Femtosecond Fiber Bragg Grating</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","Theophilus Nutsuglo","");'>Theophilus Nutsuglo</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," Yongxing Guo","");'> Yongxing Guo</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," 万欢周","");'> 万欢周</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," Haisheng Yu","");'> Haisheng Yu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," Shun’an Shen","");'> Shun’an Shen</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," 如华任","");'> 如华任</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.EN.2024-0034" target="_blank" class="mainColor">10.37188/CO.EN.2024-0034</a></font> </div> <div></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN.2024-0034" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">6</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('2879a34f-cb0b-473e-9465-267d781d58e6');"><img src="/style/web/images/custom/icopdf.png" />PDF 489KB</a>(<span class="colorRed pdf-num">0</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250">This study presents a sensitivity-enhanced tilt sensor based on femtosecond fiber Bragg gratings (FBGs). The sensor design follows static mechanics principles, where strain increases when displaced from the neutral axis. The novel use of femtosecond FBGs further enhances the sensor’s sensitivity and reliability compared to conventional FBGs. Finite element analysis (FEA) identified the optimal distance of 4.4 mm for maximum strain. A prototype sensor was manufactured and tested within a tilt range of -30° to 30°. Experimental results show an improved sensitivity of 129.95 pm/° and linearity of 0.9997. The sensor demonstrated repeatability (error < 0.94%), creep resistance (error < 0.30%), and temperature stability (error < 0.90%). Deployed in an underground pipeline project, it successfully monitored tilt highlighting its potential for structural health monitoring (SHM).</span> <span class="extraAbstract"></span> </div>  </div>

ground station telescopes equipped with large aperture primary mirrors must be able to withstand extreme outdoor temperature. A central support scheme using room-temperature vulcanizing silicone rubber was proposed for a high-precision primary mirror with an optical aperture of 500 mm. The mirror body is made of microcry stalline material, and both of the bushing and the supporting cylinder are made of titanium alloy, and with a 1mm-thick adhesive layer, which can effectively reduce the thermal stress inside the assembly during temperature changes and while unloading the gravity of the mirror blank. The thickness and height of the adhesive layer were determined by optimization. A specially designed fixture can accurately control the shape and thickness of the adhesive layer. The ventilation holes on the bushing promote its full solidification. Simulation analysis indicates that the surface shape accuracy of the primary mirror is 4.199 nm in RMS under 40 °C temperature variation, with 13.748 nm under vertical gravity and 4.187 nm under horizontal gravity, accompanied by the maximum mirror inclination and displacement of 4.722" and 3.597 μm, and the fundamental frequency of the assembly reaches 53.45 Hz. The measured surface shape accuracy of the primary mirror is RMS 0.017λ (λ=632.8 nm). The surface can maintain high-precision after extensive heat cycling tests and vacuum coating. The central support structure can significantly improve the temperature adaptability of precise mirrors and has broad application prospects in large-scale ground optoelectronic equipment.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="fc5c5efe-472f-4418-bad1-f1f0c4ff7940" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0083-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0083-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0083-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0083" class="" target="_blank">Design and analysis of a double-layer trapezoidal groove of polarization-independent beam-combining gratings with high diffraction efficiency</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","SUN Ao","");'>SUN Ao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Rui-Peng","");'> WANG Rui-Peng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SUN Yu-Qi","");'> SUN Yu-Qi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Xin-Yu","");'> WANG Xin-Yu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Wen-Hao","");'> LI Wen-Hao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIANG Yan-Xiu","");'> JIANG Yan-Xiu</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0083" target="_blank" class="mainColor">10.37188/CO.2024-0083</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0083" target="_blank" class="mainColor">32171.14.CO.2024-0083</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0083" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">116</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0083" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">106</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('fc5c5efe-472f-4418-bad1-f1f0c4ff7940');"><img src="/style/web/images/custom/icopdf.png" />PDF 4488KB</a>(<span class="colorRed pdf-num">21</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to meet the needs of broad band, high diffraction efficiency, and polarization independence, a double-layer trapezoidal polarization-independent beam grating is proposed in this paper. Firstly, based on the strict coupled wave theory, a design model of polarimetric independent combined beam grating based on a particle swarm optimization algorithm is established, and the efficiency characteristics are optimized by randomly generating characteristic wavelengths. Then, the effects of slot depth, width ratio, side angle, and other structural parameters on the diffraction efficiency and bandwidth of single-layer and double-layer trapezoidal grating are analyzed in detail. Finally, the electric field enhancement characteristics of the two structures are analyzed and discussed. The results show that the double-layer trapezoidal polarimetric beam independent grating achieves a theoretical diffraction efficiency of more than 99% in the bandwidth range of 51 nm (<styled-content style-type="number">1038</styled-content> nm−<styled-content style-type="number">1089</styled-content> nm), and has a larger process tolerance than the traditional single-layer trapezoidal structure, which meets the bandwidth of 30 nm and the high diffraction efficiency of 98% in the tolerance range, and has lower near-field grating enhancement. It has a stronger resistance to laser damage. The proposed double-layer trapezoidal grating with wide band and high diffraction efficiency can improve the output power of laser systems, and has significant application value in the field of laser beam combination.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="e91a47be-4770-4fbe-93ef-1f2506d0370f" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0090-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0090-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0090-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0090" class="" target="_blank">Fiber bragg grating temperature and pressure sensor based on hinge lever structure</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","LIU Qiang","");'>LIU Qiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," MA Chao","");'> MA Chao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WEI Shu-hui","");'> WEI Shu-hui</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Wei","");'> LIU Wei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Jian-xin","");'> WANG Jian-xin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LV Jing-wei","");'> LV Jing-wei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LV Ting-ting","");'> LV Ting-ting</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Chao","");'> LIU Chao</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0090" target="_blank" class="mainColor">10.37188/CO.2024-0090</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0090" target="_blank" class="mainColor">32171.14.CO.2024-0090</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0090" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">70</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0090" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">42</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('e91a47be-4770-4fbe-93ef-1f2506d0370f');"><img src="/style/web/images/custom/icopdf.png" />PDF 4926KB</a>(<span class="colorRed pdf-num">15</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In this paper, a high-sensitivity temperature and pressure sensor is designed.

information capacity have attracted considerable attention from researchers. This study proposes a 2-bit tunable decoupled coded metasurface designed for the terahertz band, which utilizes the tunable properties of Dirac semimetals (DSM) to create a novel multilayer structure. By incorporating both geometric and propagating phases into the metasurface design, we can effectively control the electromagnetic wave. When the Fermi energy level of the DSM is set at 6 meV, the electromagnetic wave is manipulated by the DSM patch to operate at a frequency of 1.3 THz. Conversely, at a Fermi energy level of 80 meV, the electromagnetic wave is similarly controlled to function at a frequency of 1.4 THz. Both modes enable independent control of beam splitting under left-rotating circularly polarized (LCP) and right-rotating circularly polarized (RCP) wave excitation, resulting in the generation of vortex beams with distinct orbital angular momentum (OAM) modes. The findings of this study hold significant potential for enhancing information capacity and polarization multiplexing techniques in wireless communications.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="404aa932-4e54-447c-a6e9-6487106e8941" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0098-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0098-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0098-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0098" class="" target="_blank">Scintillation index analysis of radial Gaussian vortex beam array propagation in the atmosphere</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","ZHANG Yan-na","");'>ZHANG Yan-na</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," OU Jun","");'> OU Jun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHI Hao","");'> CHI Hao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YANG Shu-na","");'> YANG Shu-na</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0098" target="_blank" class="mainColor">10.37188/CO.2024-0098</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0098" target="_blank" class="mainColor">32171.14.CO.2024-0098</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0098" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">210</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0098" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">266</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('404aa932-4e54-447c-a6e9-6487106e8941');"><img src="/style/web/images/custom/icopdf.png" />PDF 2729KB</a>(<span class="colorRed pdf-num">25</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Beam arrays have great application value in free-space optical communication. In this paper, the light intensity evolution and the on-axis scintillation index of radial Gaussian vortex beam arrays propagating through atmospheric turbulence are analyzed using multi-phase screen simulation. The effect of initial beam parameters on the on-axis scintillation index of radial Gaussian vortex beam arrays is studied, and the on-axis scintillation index of radial Gaussian vortex beam arrays Ais a single compared with that of Gaussian vortex beam. The results indicate that in the weak fluctuation regime and when the rytov index is less than 0.5, the on-axis scintillation index of Gaussian vortex beams remains within a numerical range of less than 1, while the on-axis scintillation index of radial Gaussian vortex beam arrays is around 1. In the medium fluctuation regime, the on-axis scintillation index of the radial Gaussian vortex beam arrays is smaller than that of a single Gaussian vortex beam. The on-axis scintillation index of radial Gaussian vortex beam arrays decreases with the decrease of orbital angular momentum and the increase of radial array radius.

This paper develops a long-period fiber grating sensor based on periodic microchannels. First, a series of linear structures were etched in the cladding of a single-mode fiber by femtosecond laser micromachining. Then, the laser-modified region was selectively eroded by selective chemical etching to obtain the periodic microchannel structure. Finally, the channels were filled with polydimethylsiloxane (PDMS) to improve the spectral quality. The experimental results show that the sensor has good sensitivity in the measurement of various parameters such as temperature, stress, refractive index (RI), and bending. It has a temperature sensitivity of −55.19 pm/°C, a strain sensitivity of −3.19 pm/με, a maximum refractive index sensitivity of 540.28 nm/RIU, and a bending sensitivity of 2.65 dB/m<sup>−1</sup>. All of the measurement parameters show good linear responses. The sensor has strong application prospects in the field of precision measurement and sensing.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="e1e6716f-27b5-4b4a-8d88-6c3867a9eba8" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0122-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0122-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0122-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0122" class="" target="_blank">Improvement of signal-to-noise ratio for phase-sensitive optical time-domain reflecting system</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","WANG Zi-hao","");'>WANG Zi-hao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Zhi-kai","");'> LIU Zhi-kai</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," FENG Yu-xiang","");'> FENG Yu-xiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Cheng-long","");'> ZHANG Cheng-long</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LV Li-dong","");'> LV Li-dong</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0122" target="_blank" class="mainColor">10.37188/CO.2024-0122</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0122" target="_blank" class="mainColor">32171.14.CO.2024-0122</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0122" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">104</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0122" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">21</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('e1e6716f-27b5-4b4a-8d88-6c3867a9eba8');"><img src="/style/web/images/custom/icopdf.png" />PDF 4187KB</a>(<span class="colorRed pdf-num">6</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>The sensitivity of phase-sensitive optical time-domain reflecting (Φ-OTDR) system is limited by the intrinsic system noise such as the phase noise of the laser, the spontaneous emission noise of the erbium-doped fiber amplifier, and the shot noise and thermal noise of the photodetector, as well as the random noise in the environment. Therefore, the noise reduction algorithms based on the optical time-domain reflecting data is investigated to improve the signal-to-noise ratio (SNR) of the system without degrading the frequency response range. And the Savitzky-Golay smoothing algorithm is proposed by selecting a slidable window with fixed-length to process OTDR data for the SNR improvement, while maintaining the system sampling frequency, and then, the experimental system is built to demonstrate the results. The experimental results show that by using the Savitzky-Golay smoothing algorithm, the SNR of the system is improved by 5.41dB relative to that by difference method with the original data, and the SNR is improved by 3.39dB and 5.05dB respectively, compared to the commonly used cumulative averaging method and sliding averaging method. It is demonstrated that the Savitzky-Golay smoothing algorithm can improve the sensitivity and accuracy of the Φ-OTDR system, which helps to accurately sense weak vibration events and reduce false alarm rate.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="f3dc593a-7fa5-4dd1-98fc-fb98c452640b" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0006-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0006-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0006-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN-2024-0006" class="" target="_blank">Effect of GaInP and GaAsP inserted into waveguide/barrier interface on carrier leakage in InAlGaAs quantum well 808-nm laser diode</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","FU Meng-jie","");'>FU Meng-jie</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," DONG Hai-liang","");'> DONG Hai-liang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIA Zhi-gang","");'> JIA Zhi-gang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIA Wei","");'> JIA Wei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIANG Jian","");'> LIANG Jian</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XU Bing-she","");'> XU Bing-she</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.EN-2024-0006" target="_blank" class="mainColor">10.37188/CO.EN-2024-0006</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.EN-2024-0006" target="_blank" class="mainColor">32171.14.CO.EN-2024-0006</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0006" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">147</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0006" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">32</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('f3dc593a-7fa5-4dd1-98fc-fb98c452640b');"><img src="/style/web/images/custom/icopdf.png" />PDF 1288KB</a>(<span class="colorRed pdf-num">16</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>There is nonradiative recombination in waveguide region owing to severe carrier leakage, which in turn reduces output power and wall-plug efficiency.

This method first utilizes epipolar constraints to identify multiple potential matching points, and then filters out the correct matching points through the spatial equations of the multi-line laser. The process of 3D reconstruction is then achieved using these matching points. However, due to the inevitable noise affecting the multi-line laser lines, the extracted laser center coordinates often contain certain errors. These errors can lead to the inability to obtain high-precision 3D data when using matching points found based on epipolar constraints for 3D reconstruction directly. To address this issue, this paper proposes a method based on geometric estimation to achieve 3D reconstruction of multi-line lasers. First, by calibrating the quadratic surface equations of the multi-line laser, combined with the binocular epipolar constraint method, the initial matching points of the multi-line laser can be calculated. After finding the correct initial matching points, a geometric distance minimization estimation model is established using the distance constraint from points to epipolar lines. This geometric distance refers to the distance from the laser center points in the left and right images to their corresponding epipolar lines. Through this geometric distance minimization optimization estimation, new matching points that better conform to the epipolar constraints can be recalculated. Finally, these new matching points are used to complete the 3D reconstruction of the multi-line laser. Compared to the traditional method based on epipolar constraints, the algorithm proposed in this paper performs better in terms of matching and accuracy.The accuracy of the final 3D reconstruction can reach about 0.02mm. With this method, the overall accuracy of binocular multi-line laser reconstruction can be significantly improved, thereby obtaining more accurate and reliable 3D data.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="39678448-9cf0-4c73-9279-2e63a4c888d1" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0170-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0170-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0170-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0170" class="" target="_blank">The influence of second-order pump seed light on third-order Raman fiber amplifier</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","CHEN Tong","");'>CHEN Tong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Wei","");'> LIU Wei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YANG Yue","");'> YANG Yue</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Yang","");'> LI Yang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LONG Han","");'> LONG Han</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WU Jian-jun","");'> WU Jian-jun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XIANG Min","");'> XIANG Min</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHENG Ju-xin","");'> CHENG Ju-xin</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0170" target="_blank" class="mainColor">10.37188/CO.2024-0170</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0170" target="_blank" class="mainColor">32171.14.CO.2024-0170</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0170" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">50</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0170" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">19</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('39678448-9cf0-4c73-9279-2e63a4c888d1');"><img src="/style/web/images/custom/icopdf.png" />PDF 1641KB</a>(<span class="colorRed pdf-num">2</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Third-order Raman fiber amplifier is used in long-haul unrepeatered optical transmission due to its higher gain and lower noise figure. Third-order Raman fiber amplifier is an advanced technology in Raman amplification, and currently there is very limited research on it in China. The relationship between the pump configuration and performance of the amplifier is not clear yet. Therefore, this paper analyzes the influence of second-order pump seed light on third-order Raman fiber amplifiers through experiments. Firstly, the feasibility of not using second-order pump seed light is qualitatively analyzed. Then it is experimentally verified that in the absence of second-order pump seed light, the third-order Raman fiber amplifier can still achieve signal light gain, but its efficiency will decrease. A 47-channel 200 km wavelength division multiplexing transmission system is constructed, the experimental results show that the third-order Raman fiber amplifier can amplify the signal light without second-order pump seed light, but the introduce of the second-order pump seed light can significantly improve its performance. A second-order pump seed light with only 25 mW can achieve a minimum signal power gain of 3.7 dB, an average gain of 6 dB, and an average signal-to-noise ratio gain of 1.6 dB. Eliminating second-order pump seed light can reduce costs, but introducing a second-order pump seed light brings significant performance improvements to third-order Raman amplifiers.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="2926bd3c-72ab-424f-868b-019977e44b1a" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0152-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0152-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0152-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0152" class="" target="_blank">Research on CGH null compensation testing of high-order coaxial aspherical surface</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","WANG Shen","");'>WANG Shen</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Quan","");'> LIU Quan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," GUO Cheng-li","");'> GUO Cheng-li</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YAN Lisong","");'> YAN Lisong</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0152" target="_blank" class="mainColor">10.37188/CO.2024-0152</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0152" target="_blank" class="mainColor">32171.14.CO.2024-0152</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0152" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">59</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0152" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">37</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('2926bd3c-72ab-424f-868b-019977e44b1a');"><img src="/style/web/images/custom/icopdf.png" />PDF 5990KB</a>(<span class="colorRed pdf-num">7</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to solve the problem of high-precision surface map testing of coaxial high-order aspherical surface, a null compensation testing method based on CGH is proposed in this paper.

Using dual-frequency laser interferometer feedback table position to splicing interference fringes accurately, the measurement error will inevitably introduce grating engraving error and reduce the diffraction wavefront quality of grating. The intrinsic error caused by the structure of laser interferometer is analyzed, and the evaluation method of the intrinsic error index of laser interferometer in complex environment is proposed. The theoretical models of dead path error and measuring optical path variation error combined with actual working conditions and empirical formulas are established. By constructing translation and rotation operators, the coupling relationship between rotation and displacement of any point of the table is deduced, and the measurement errors under different table attitude roll angles are simulated. The displacement error experiment and grating scanning exposure experiment are carried out. The experimental results show that the displacement error is consistent with the theoretical calculation results. The diffraction wavefront of the 200 mm×200 mm grating is 0.278λ@632.8nm. The analytical method in this paper connects the transmission link between the grating diffraction wavefront and the measurement error, and lays a theoretical and experimental foundation for the fabrication of meter-size nano-precision holographic gratings.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="301907f1-c1c8-4684-a150-d965653f3eeb" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0115-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0115-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0115-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0115" class="" target="_blank">Non-destruction Detection of jelly orange granulation disease using laser Doppler vibrometry</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","LIU Zhi","");'>LIU Zhi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LAI Qing-rong","");'> LAI Qing-rong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Tian-yu","");'> ZHANG Tian-yu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Bin","");'> LI Bin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SONG Yun-feng","");'> SONG Yun-feng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHEN Nan","");'> CHEN Nan</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0115" target="_blank" class="mainColor">10.37188/CO.2024-0115</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0115" target="_blank" class="mainColor">32171.14.CO.2024-0115</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0115" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">101</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0115" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">46</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('301907f1-c1c8-4684-a150-d965653f3eeb');"><img src="/style/web/images/custom/icopdf.png" />PDF 3944KB</a>(<span class="colorRed pdf-num">6</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Granulation is a common internal disease of citrus fruits, and it is difficult to identify the fruits with this disease from their external features. In this study, an acoustic vibration experimental setup was constructed using a micro-laser Doppler vibrometer (micro-LDV) and a resonance speaker. This was used to collect vibration response signals of ‘Aiyuan 38’ jelly orange. The one-dimensional vibration response signals were converted into vibration multi-domain images, and a Resnet-Transformer network (ResT) was constructed to extract deeper features from the vibration multi-domain images for identifying granulation disease in jelly oranges. In this paper, the ResT, Resnet50, and Vision Transformer (ViT) models were trained using vibration multi-domain images, and their performances were compared. Then, partial least squares discriminant analysis (PLS-DA) and support vector machine (SVM) models were trained using vibration multi-domain image texture features or vibration spectrum features, and the performance was compared with the ResT model. The results show that the ResT model trained using vibration multi-domain images can achieve accurate identification of jelly orange granulation disease with 98.61% detection accuracy, 0.986 F1, 0.986 precision, and 0.986 recall.

This model is required for the development of polarization imaging instruments. Based on the P-G model, it first analyzes serious shadow masking effects. These effects occur when light is incident at a large angle. It then optimizes the shadow masking function using the spherical trigonometry formula. This optimization equates the specular reflection point to a three-dimensional sphere. Due to the unique dispersion characteristics of different targets, a new bidirectional polarization distribution function (BPDF) model is introduced. This model replaces the traditional BRDF parameter affected by wavelength and body scattering. The new BPDF model integrates diffuse reflection and body scattering. In the experimental stage, the accuracy of line polarization degree is calibrated. The line polarization degree of typical airport ground material is fitted with model parameters. This fitting is based on the dynamic TS algorithm through multi-angle BRDF experiments. The fitting model's six parameters are used to obtain the root mean square roughness parameter. This process verifies the validity of the modified BPDF model. In the simulation stage, the root mean square error (RMSE) is used as the accuracy index. The modified BPDF model, control model, and experimental results are compared. This comparison analyzes the effects of detection angle, azimuth angle, and incidence angle on polarization characteristics. The accuracies of four experimental targets improved by 4.39%, 4.00%, 4.17%, and 5.26%. This is compared with the control model. The root mean square error is less than 0.05 for large detection angles. This allows the modified model to study polarization characteristics of rough materials like airport ground targets. Finally, the effect of fitting parameters on polarization characteristics is simulated. Results show that line polarization is positively related to the refractive index. It is inversely related to surface roughness. The accuracy of the modified BPDF model is thus proved. This provides ideas for studying polarization characteristics of airport ground targets.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="4a809845-7aac-4ae7-ad86-fe1a54333f89" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0155-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0155-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0155-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0155" class="" target="_blank">Recognition method for vortex beams orbital angular momentum with imbalanced label</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","YU Hai-yang","");'>YU Hai-yang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SHANG Fan-hua","");'> SHANG Fan-hua</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Yu-xing","");'> WANG Yu-xing</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Da-tao","");'> WANG Da-tao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHEN Chun-yi","");'> CHEN Chun-yi</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0155" target="_blank" class="mainColor">10.37188/CO.2024-0155</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0155" target="_blank" class="mainColor">32171.14.CO.2024-0155</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0155" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">51</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0155" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">33</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('4a809845-7aac-4ae7-ad86-fe1a54333f89');"><img src="/style/web/images/custom/icopdf.png" />PDF 1611KB</a>(<span class="colorRed pdf-num">7</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>To identify orbital angular momentum (OAM) with imbalanced label, a derived model based on global cost SMOTE and deep extreme learning machine (DELM) has been proposed. Different from typical machine learning methods, the proposed model can obtain the analytical expression of the mapping model. It will avoid the repeated parameter optimization process, thus building a suitable model for time-varying engineering applications. In the data generation stage, the inverse matrix of covariance is used to remove the dimension influence, and the differences of the same sample set are measured effectively. In the model selection stage, considering the transmission characteristics of light signal in atmosphere turbulence, the DELM is adopted to quantify the mapping relationship between light spots and labels. Then the FISTA algorithm helps to calculate the analytical expression of the model. Experiments are carried out on different intensity atmospheric turbulence data sets. The representative comparative methods include WELM and K-nearest neighbor. Experimental results show that the root mean square error(RMSE) of the proposed method achieve <styled-content style-type="number">0.2049</styled-content> and <styled-content style-type="number">0.0894</styled-content>, which are superior to the comparison method under different turbulence intensities.

This approach enhances detection efficiency and reduces system complexity. Here, the principles of the multibeam interference process and construction of a co-phasing detection module based on direct optical fiber connections were analyzed using wavefront optics theory. Error analysis was conducted on the system surface obtained through multipath interference. Potential applications of the interferometric method were explored. Finally, the principles of the multipath interference process were experimentally revealed. Evidently, flat-field calibration and incoherent digital synthesis enhanced the fringe contrast to more than 0.4, with the dynamic range exceeding 10 times the working center wavelength (<styled-content style-type="number">1550</styled-content> nm). Moreover, a resolution better than one-tenth of the working center wavelength (<styled-content style-type="number">1550</styled-content> nm) was achieved. Simultaneous three-beam interference can be achieved, leading to a 50% improvement in detection efficiency. This method can effectively enhance the efficiency of sparse aperture telescope co-phasing, meeting the requirements for observations of 8–10 m telescopes.

Focusing on the most prevalent constant bias fault, this paper proposes an LMI-based fault observer design method, aiming to enhance the reliability of fault detection and strengthen the stability and anti-interference capabilities of the FSM. Firstly, the model identification method based on Hankel matrix is employed to identify the two-axis fast steering mirror model including the coupling effect. Then, the fault model of the fast steering mirror system is established, and the fault observer of the fast steering mirror is designed by using the LMI-based method. Finally, the proposed method is verified through simulations and experiments. The results indicate that when both axes of the fast steering mirror have constant bias faults in the actuators and sensors, the Riccati-based fault observer can only detect the fault in one axis, while the LMI-based fault observer can detect faults within 0.1 seconds after the fault of the X-axis occurs, and detect faults within 0.06 seconds after the fault of the Y-axis occurs.

It is found that the reliability of phase unwrapping is closely related to the allocation of fringe frequencies. Consequently, an optimal fringe frequency allocation strategy is proposed.

This paper proposes a novel hyperspectral imaging system that utilizes a shared primary and secondary mirror design, along with a coaxial five-mirror optical path for multi-channel separation. By integrating Offner convex grating spectroscopy, the system enables hyperspectral detection from the visible to the long-wave infrared spectrum. Design results indicate that with a primary mirror diameter of <styled-content style-type="number">1000</styled-content> mm at an altitude of 500 km, the spatial resolution in the visible and short-wave bands exceed 2 m, in the mid-wave band exceed 3 m, in the long-wave band exceed 6m, and the panchromatic resolution is better than 1 m. The system achieves a full field of view of 2.3°, accommodating a swath width of 20 km for detection.To enhance the system's capabilities for aberration and distortion correction, high-order aspheric elements are incorporated to create a telecentric optical path, ensuring optimal matching between the telescope and the spectrometer. Furthermore, we propose housing the spectrometer module in a cooling chamber to effectively mitigate the impact of background radiation from the optical structure on image quality.The final design demonstrates excellent imaging quality, a simple layout, and a compact structure, enabling the simultaneous acquisition of high spectral information across the entire spectrum. This system has broad applications in satellite-based earth observation and imaging.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="32dbbc90-48fc-4f5e-86a2-71ccd0ee2918" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0139-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0139-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0139-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0139" class="" target="_blank">Research on Back-illuminated CMOS Image Sensor Irradiated by Pulsed Laser</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","QIAN Fang","");'>QIAN Fang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," PENG Jia-qi","");'> PENG Jia-qi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XU Yong-bo","");'> XU Yong-bo</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0139" target="_blank" class="mainColor">10.37188/CO.2024-0139</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0139" target="_blank" class="mainColor">32171.14.CO.2024-0139</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0139" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">57</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0139" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">18</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('32dbbc90-48fc-4f5e-86a2-71ccd0ee2918');"><img src="/style/web/images/custom/icopdf.png" />PDF 2993KB</a>(<span class="colorRed pdf-num">2</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>CMOS image sensor is one of the most widely used sensors, widely used in aerospace, medical imaging, industrial detection, military reconnaissance and other fields.The laser interference and damage of CMOS image sensor has also become a research hotspot in related fields at home and abroad. To investigate the impact of pulsed laser on back-illuminated CMOS image sensors, this paper selects the Sony IMX178 back-illuminated CMOS image sensor as the target material. Based on the heat conduction equation, the finite element simulation software COMSOL Multiphysics is used to compare and calculate the temperature distribution of the CMOS image sensor under the irradiation of single-pulse lasers with different parameters.The calculation results indicate that the point damage thresholds of the sensor under the effects of single-pulse lasers at 532 nm (1 ns), <styled-content style-type="number">1064</styled-content> nm (1 ns), 532 nm (30 ps), and <styled-content style-type="number">1064</styled-content> nm (30 ps) are respectively 61.12 mJ/cm<sup>2</sup>, 75.76 mJ/cm<sup>2</sup>, 31.83 mJ/cm<sup>2</sup>, and 37.43 mJ/cm<sup>2</sup>.Subsequently, an experimental study on the laser irradiation effects of back-illuminated CMOS image sensors was conducted.The experimental results demonstrate that the image sensor exhibits a lower damage threshold under the influence of 532 nm pulsed lasers compared to <styled-content style-type="number">1064</styled-content> nm pulsed lasers; picosecond pulsed lasers, with higher peak power compared to nanosecond pulsed lasers, are more prone to causing point damage; the calculated point damage thresholds are in good agreement with the experimental results.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="e6363929-ba8f-41f4-b3a1-ba2359560311" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0125-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0125-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0125-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0125" class="" target="_blank">Modulation of a Kretschmann-type sensor’s spectra using TiO<sub>2</sub>/PSS thin films</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","YANG Yan","");'>YANG Yan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Hui-min","");'> ZHANG Hui-min</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Xu-lin","");'> ZHANG Xu-lin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YAN Xiu-jing","");'> YAN Xiu-jing</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CAI Lei","");'> CAI Lei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Qiu-shun","");'> LI Qiu-shun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," DONG Wen-fei","");'> DONG Wen-fei</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0125" target="_blank" class="mainColor">10.37188/CO.2024-0125</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0125" target="_blank" class="mainColor">32171.14.CO.2024-0125</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0125" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">63</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0125" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">37</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('e6363929-ba8f-41f4-b3a1-ba2359560311');"><img src="/style/web/images/custom/icopdf.png" />PDF 3655KB</a>(<span class="colorRed pdf-num">8</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to explore the effect of titanium dioxide (TiO<sub>2</sub>)/poly(sodium 4-styrenesulfonate) (PSS) nanofilms on the Kretschmann-type surface plasmon resonance sensor, the spectral changes of the sensor after depositing TiO<sub>2</sub>/PSS nanofilms of different thicknesses were systematically studied. The reasons for the spectral changes were further explained and discussed theoretically. First, TiO<sub>2</sub>/PSS multilayer films were deposited in situ on the surface of the glass chip sputtered with a gold layer via electrostatic layer-by-layer self-assembly technology, and the corresponding reflection spectra of the sensor were recorded in real time. Then, the original reflectance spectrum data was processed to make the spectral curve clearer and more visible. Finally, the experimental results were simulated and analyzed using MATLAB software programming. The results show that as the number of TiO<sub>2</sub>/PSS bilayers increased, four different types of reflection peaks successively appeared in the sensor’s spectra in the 450−900 nm wavelength range. The four types of reflection peaks correspond to the surface plasmon resonance mode, the first-order mode, the second-order mode, and the third-order mode of the transverse magnetic mode of the sensor, respectively. This indicates that the Kretschmann-type sensor’s sensing mode and reflection spectrum type can be modulated by controlling the thickness of TiO<sub>2</sub>/PSS thin films.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="5986b351-b785-4852-8d9b-bfc944806e90" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0147-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0147-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0147-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0147" class="" target="_blank">Infrared and visible image fusion guided by cross-domain interactive attention and contrast learning</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","DI Jing","");'>DI Jing</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIANG Chan","");'> LIANG Chan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Ji-zhao","");'> LIU Ji-zhao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIAN Jing","");'> LIAN Jing</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0147" target="_blank" class="mainColor">10.37188/CO.2024-0147</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0147" target="_blank" class="mainColor">32171.14.CO.2024-0147</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0147" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">100</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0147" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">48</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('5986b351-b785-4852-8d9b-bfc944806e90');"><img src="/style/web/images/custom/icopdf.png" />PDF 9245KB</a>(<span class="colorRed pdf-num">6</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Aiming at the problems in existing infrared and visible image fusion methods, such as the difficulty in fully extracting and preserving the source image details, contrast, and blurred texture details, this paper proposes an infrared and visible image fusion method guided by cross-domain interactive attention and contrastive learning. First, a dual-branch skip connection detail enhancement network was designed to separately extract and enhance detail information from infrared and visible images, using skip connections to prevent information loss and generate enhanced detail images. Next, a fusion network combining a dual-branch encoder and cross-domain interactive attention module was constructed to ensure sufficient feature interaction during fusion, and the decoder was used to reconstruct the final fused image. Then, a contrastive learning network was introduced, performing shallow and deep attribute and content contrastive learning from the contrastive learning block, optimizing feature representation, and further improving the performance of the fusion network. Finally, to constrain network training and retain the inherent features of the source images, a contrast-based loss function was designed to assist in preserving source image information during fusion. The proposed method is qualitatively and quantitatively compared with current state-of-the-art fusion methods. Experimental results show that the eight objective evaluation metrics of the proposed method significantly outperform the comparison methods on the TNO, MSRS, and RoadSence datasets.

The simulated dynamic L-type matching network can inject 60 kW RF power into 16 discharge tubes and achieve a reflectivity of less than 1% in the range of total load impedance of 12.81 Ω~49.94 Ω. A single-tube RF discharge experimental device was built, and the reflectivity of the dynamic L-type matching network was measured as less than 1% at 4 kW injection power, which was consistent with the simulation results.

Taking advantage of the characteristics of HCN with high absorption intensity at wavelength <styled-content style-type="number">1531</styled-content> nm and less interference by common gases in the atmosphere, the HCN concentration information was obtained by second harmonic signal processing. A high-precision flow controller is used to obtain HCN from 5×10<sup>-6</sup> mol/mol to 20×10<sup>-6</sup> mol/mol using a 99% standard nitrogen dilution ratio, and the measurement data is calibrated. The experimental results show that the linear correlation coefficient R2 of HCN reaches 0.9978. Then, the effects of different coal types, heating rate, and coal particle size on pyrolysis were discussed, as well as the relationship between the coal samples’ weight loss rate and the amount of HCN concentration released. The release characteristics of HCN and the nonisothermal pyrolysis kinetics in the volatile matter of three coal types with different coalification degrees were analyzed. A pyrolysis kinetic model was established by dividing the pyrolysis temperature stages, and the activation energy and frequency factors of varying coal types at different heating rates were calculated. The results show that the HCN emission is closely related to the degree of coalification and nitrogen content of coal types. The lower the degree of coalification, the higher the nitrogen content and the more HCN emitted. Under the fixed pyrolysis final temperature, an increase in the heating rate will increase the amount of HCN released. With the decrease in coal particle size, the time of HCN release from the pyrolysis reaction will be delayed, and the HCN concentration will decrease. There was a different correspondence between the release of HCN concentration and the coal samples’ weight loss rate in different pyrolysis stages. The more intense the pyrolysis reaction, the greater the proportion of HCN concentration released to the coal samples’ weight loss rate. This study provides an important experimental basis for further evaluation of the toxicity of HCN during coal pyrolysis reactions.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="1168cca3-a4a9-42e1-93c4-0d5afede8d03" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0094-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-2024-0094-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-2024-0094-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0094" class="" target="_blank">Study of the scattering model of micro-defects on cavity mirrors in cavity ring-down spectroscopy instruments</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","REN Yi-jie","");'>REN Yi-jie</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Zheng-tao","");'> ZHANG Zheng-tao</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.2024-0094" target="_blank" class="mainColor">10.37188/CO.2024-0094</a></font> </div> <div>cstr: <a href="https://cstr.cn/32171.14.CO.2024-0094" target="_blank" class="mainColor">32171.14.CO.2024-0094</a></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0094" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">63</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0094" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">53</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('1168cca3-a4a9-42e1-93c4-0d5afede8d03');"><img src="/style/web/images/custom/icopdf.png" />PDF 6549KB</a>(<span class="colorRed pdf-num">5</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Microdefects in cavity mirrors utilized in cavity ring-down spectroscopy (CRDS) adversely affect measurement accuracy.

In order to reduce the detection limit of REEs in liquid samples by laser-induced breakdown spectroscopy (LIBS), superhydrophobic array-assisted spark-enhanced laser-induced breakdown spectroscopy (SHA-SD-LIBS) was used in this study to determine the REEs in liquid-phase samples. Optimal experimental conditions were chosen to measure the REEs with the parameters of La II 394.91 nm, Er 402.051 nm, Ce II 418.66 nm, Nd II 424.738 nm, Gd II 443.063 nm, and Pr 492.46 nm as the characteristic spectral lines, and the calibration curves were established for the quantitative analysis of the solutions of six rare earth elements (La, Er, Ce, Nd, Gd and Pr) with different concentrations. The results show that the fit coefficients R² of the calibration curves were above 0.99. The corresponding detection limits were 0.007 μg/mL, 0.045 μg/mL, 0.011 μg/mL, 0.019 μg/mL, 0.041 μg/mL, and 0.008 μg/mL. The proposed method is a simple, low-cost, and highly efficient way to improve the quality of the liquid-phase sample. Compared with the conventional LIBS method, the proposed method can significantly reduce the detection limit of REEs in liquid phase samples with simple sample preparation and low cost. It can serve as a basis for new rapid and accurate methods of measuring rare earth element types and contents in liquid phase samples.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="f2d6a4ef-8b03-47cd-9667-ebb568d89fbe" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0026-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0026-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0026-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN-2024-0026" class="" target="_blank">Detection method of splicing detector based on channel spectral dispersion</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","ZHAO Hong-chao","");'>ZHAO Hong-chao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Xiao-qian","");'> ZHANG Xiao-qian</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," AN Qi-chang","");'> AN Qi-chang</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.EN-2024-0026" target="_blank" class="mainColor">10.37188/CO.EN-2024-0026</a></font> </div> <div></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0026" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">69</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0026" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">26</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('f2d6a4ef-8b03-47cd-9667-ebb568d89fbe');"><img src="/style/web/images/custom/icopdf.png" />PDF 5659KB</a>(<span class="colorRed pdf-num">7</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>For segmented detectors, surface flatness is critical as it directly influences both energy resolution and image clarity.

By optimizing the structural configuration and selecting suitable bonding processes, the reliability of the telescope system is enhanced. The research indicates that the use of J-133 adhesive achieves the best performance, with a bonding layer thickness of 0.30 mm and a metal substrate surface roughness of Ra 0.8. These findings significantly enhance the reliability of the optical system while minimizing potential risks.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="01636abb-8223-4c53-9e8d-a2d9cc02ef57" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0007-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0007-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0007-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN-2024-0007" class="" target="_blank">Phase distortion correction of fringe patterns in spaceborne Doppler asymmetric spatial heterodyne interferometry</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","PEI Hui-yi","");'>PEI Hui-yi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIANG Lun","");'> JIANG Lun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Jin-jiang","");'> WANG Jin-jiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CUI Yong","");'> CUI Yong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," FANG Yuan-xiang","");'> FANG Yuan-xiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Jia-ming","");'> ZHANG Jia-ming</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHEN Ci","");'> CHEN Ci</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.EN-2024-0007" target="_blank" class="mainColor">10.37188/CO.EN-2024-0007</a></font> </div> <div></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0007" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">89</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0007" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">93</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('01636abb-8223-4c53-9e8d-a2d9cc02ef57');"><img src="/style/web/images/custom/icopdf.png" />PDF 755KB</a>(<span class="colorRed pdf-num">19</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>As an advanced technology for observing atmospheric winds, the spaceborne Doppler Asymmetric Spatial Heterodyne (DASH) interferometer also encounters challenges associated with phase distortion, particularly in limb sounding scenarios. This paper discusses interferogram modeling and phase distortion correction techniques for spaceborne DASH interferometers. The modeling of phase distortion interferograms with and without Doppler shift for limb observation was conducted, and the effectiveness of the analytical expression was verified through numerical simulation. The simulation results indicate that errors propagate layer by layer while using the onion-peeling inversion algorithm to handle phase-distorted interferograms. In contrast, the phase distortion correction algorithm can achieve effective correction. This phase correction method can be successfully applied to correct phase distortions in the interferograms of the spaceborne DASH interferometer, providing a feasible solution to enhance its measurement accuracy.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="be8b72f5-37e6-413c-b20a-1fc53ac7db8c" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0027-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0027-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0027-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN-2024-0027" class="" target="_blank">Numerical simulations on the photoelectric performance of AlGaN-based ultraviolet VCSELs with a slope-shaped p-type layer</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","Wen Xin-xin","");'>Wen Xin-xin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIA Wei","");'> JIA Wei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAI Guang-mei","");'> ZHAI Guang-mei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," DONG Hai-liang","");'> DONG Hai-liang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Chao","");'> ZHAO Chao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Tian-bao","");'> LI Tian-bao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XU Bing-she","");'> XU Bing-she</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.EN-2024-0027" target="_blank" class="mainColor">10.37188/CO.EN-2024-0027</a></font> </div> <div></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0027" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">83</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0027" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">48</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('be8b72f5-37e6-413c-b20a-1fc53ac7db8c');"><img src="/style/web/images/custom/icopdf.png" />PDF 2064KB</a>(<span class="colorRed pdf-num">16</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Owing to the low p-type doping efficiency of GaN-based ultraviolet (UV) vertical-cavity surface-emitting laser (VCSEL) hole injection layers (HILs), effective hole injection in multi-quantum wells (MQW) is not achieved, significantly limiting the photoelectric performance of UV VCSELs. By improving hole injection efficiency, the hole concentration in the HIL is increased, and the hole barrier at the electron barrier layer (EBL)/HIL interface is decreased. This minimises the hindering effect of hole injection. In this study, we developed a slope-shaped HIL and an EBL structure in AlGaN-based UV VCSELs. A mathematical model of this structure was established using a commercial software, photonic integrated circuit simulator in three-dimension (PICS3D). We conducted simulations and theoretical analyses of the band structure and carrier concentration. Introducing polarisation doping through the Al composition gradient in the HIL enhanced the hole concentration, thereby improving the hole injection efficiency. Furthermore, modifying the EBL eliminated the abrupt potential barrier for holes at the HIL/EBL interface, smoothing the valence band. This improved the stimulated radiative recombination rate in the MQW, increasing the laser power. Therefore, the sloped p-type layer can enhance the optoelectronic performance of UV VCSELs.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> <div class="article-list article-list-latest" id="83daf4ff-0142-4e36-a2e7-c0127ddc5947" > <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0024-1.jpg"> <img src="/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0024-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/newcreate/CO-EN-2024-0024-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN-2024-0024" class="" target="_blank">351 mW of 275 nm continuous wave generation in a Pr:YLF laser pumped by a blue laser diode at 444.2 nm</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","ZHENG Quan","");'>ZHENG Quan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XIAO Hui-dong","");'> XIAO Hui-dong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHEN Xi","");'> CHEN Xi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Yan","");'> WANG Yan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Yu-ning","");'> WANG Yu-ning</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Hui-zhen","");'> LIU Hui-zhen</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," TIAN Dong-he","");'> TIAN Dong-he</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Jin-yan","");'> WANG Jin-yan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YAO Yi","");'> YAO Yi</a> </span> </div> <div class="article-list-time latest_info"> <div class="clearfix"> <font class="colorRed"><i class="current_state_en colorRed"></i></font> <font class="latest_update_span" style="display:none;">, <i>Available online</i>  <span class="latest_update"></span>,</font> <font> doi: <a href="https://doi.org/10.37188/CO.EN-2024-0024" target="_blank" class="mainColor">10.37188/CO.EN-2024-0024</a></font> </div> <div></div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0024" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">60</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0024" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">68</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('83daf4ff-0142-4e36-a2e7-c0127ddc5947');"><img src="/style/web/images/custom/icopdf.png" />PDF 563KB</a>(<span class="colorRed pdf-num">14</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>This paper describes what is thought to be the first generation of a continuous wave deep ultraviolet laser at 275 nm by efficient frequency doubling of a blue-diode-pumped Pr:YLF laser at 550 nm.

The initial structure of the optical system is obtained according to theoretical calculation, and the optical parameters are further detailed by optical design software.

The field angle of the mid-wave optical system is ±0.65°, the focal length is 750mm, the entry pupil size is 300mm, the MTF is close to the diffraction limit, and the distortion is less than 1%.

Therefore, developing a Terahertz wave detection optical imaging system holds substantial significance and wide application prospects. Firstly, we refer to the structure of Tessar objective lens, which consists four lenses. The balance equations of aberration for the system were established through the application of the aberration theory of the paraxial optical system. Subsequently, we provide a solution function and method of the initial structure parameters of the system. Then, we combine it with optical design software to further correct the aberration of the system. Finally, we design a Terahertz wave detection optical imaging system with a large aperture. The optical system consists of four coaxial refractive lenses with a total focal length of 70 mm, an F-number of 1.4, and a full field of view angle of 8°. The value of modulation transfer function (MTF) in the range of full field of view angle is greater than 0.32 at the Nyquist frequency of 10 lp/mm, and the root mean square (RMS) radius of the diffused spot in each field of view is less than the airy disk radius. Finally, the paper analyzes and discusses the various tolerance types of the system. The results indicate that the Terahertz wave detection optical imaging system, designed in this paper, has a large aperture, a simple, compact form, a lightweight structure, excellent imaging performance and simple processing, which meets the design requirements, and it has important applications in the field of high-resolution detection and other fields within the Terahertz wave band.</p></span> <span class="extraAbstract"></span> </div>  </div> </div> </div> </div> </div> </div>   <div class="tab-pane fade articleListBox active in" id="current"> <div id="lan">  <div class="toolBoxBorder"> <div class="toolBox1 clearfix"> </div> <div class="toolBox2 clearfix"> <label class="chooseAll pull-left"> <input type="checkbox" value="" class="checkAll"/>Select All </label> <div class="derived fr clear"> <i id="export" data-toggle="modal" data-target="#exportCitationModal" title="Export" class="iconfont icon-daochu4"></i> <i id="ReferencePaper" data-toggle="modal" data-target="#ReferenceFormat" title="Reference Paper" class="iconfont icon-yinyong1"></i> </div> </div> </div> <div class="article-list-journalg" id="c_1"> <a href="javascript:void(0);">Original Article</a> </div> <div class="article-list" id="d2ae635f-9c65-4660-9dd7-b79bc84f99f4"> <div class="article-list-left"><input name="journalArticleCheck" value="d2ae635f-9c65-4660-9dd7-b79bc84f99f4" type="checkbox" checkArticleId="d2ae635f-9c65-4660-9dd7-b79bc84f99f4"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0068-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0068-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0068-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0068" class="" target="_blank">Design and analysis of the double-interface liquid lens based on a combination structure</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","LIU Yue","");'>LIU Yue</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," KONG Mei-mei","");'> KONG Mei-mei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XU Chun-sheng","");'> XU Chun-sheng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," DONG Yuan","");'> DONG Yuan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," XUE Yin-yan","");'> XUE Yin-yan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Ming-yang","");'> LI Ming-yang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Shu-han","");'> ZHANG Shu-han</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1255-1264.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0068" target="_blank" class="mainColor">10.37188/CO.2024-0068</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0068" target="_blank" class="mainColor">32171.14.CO.2024-0068</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0068" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">278</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0068" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">141</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('d2ae635f-9c65-4660-9dd7-b79bc84f99f4');"><img src="/style/web/images/custom/icopdf.png" />PDF 2987KB</a>(<span class="colorRed pdf-num">116</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to improve the image quality and variable range of focal length of liquid lenses, a double-interface liquid lens based on a combination structure is designed utilizing dielectrophoretic and hydraulic drive mechanisms, which mainly consists of a dielectrophoretic double-liquid lens and a PDMS membrane liquid lens.

Based on the traditional frequency-thermal tuning methods, we explore the frequency and phase parameter characteristics of a self-injection locked laser. We propose an improved algorithm which adds self-injection locking phase compensation and DFB chip current compensation during frequency-thermal tuning methods. Experimental validation of this algorithm is conducted on a FP micro-cavity self-injection locked laser. The laser operates at a wavelength of <styled-content style-type="number">1550</styled-content> nm with a 3 dB linewidth of 785 Hz, achieving frequency-thermal tuning methods of the FP micro-cavity using a pair of heating resistors. The improved algorithm is implemented within the microcontroller program of the laser's original drive control circuit. No modifications are made to the hardware components of the laser. Ultimately, a continuous frequency tuning range of 6 GHz is realized. This work provides a simple, efficient, and stable frequency-tuning solution for self-injection-locked lasers, demonstrating high practicality and promising market prospects.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="1a3e8c4e-d0fd-446c-9add-d80d00d5c8f9"> <div class="article-list-left"><input name="journalArticleCheck" value="1a3e8c4e-d0fd-446c-9add-d80d00d5c8f9" type="checkbox" checkArticleId="1a3e8c4e-d0fd-446c-9add-d80d00d5c8f9"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0014-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0014-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0014-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0014" class="" target="_blank">Detection method of weak ship wake signals based on the synchronous accumulation method</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","ZONG Si-guang","");'>ZONG Si-guang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," DUAN Zi-ke","");'> DUAN Zi-ke</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Xin","");'> ZHANG Xin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YU Yang","");'> YU Yang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Bai-xiong","");'> WANG Bai-xiong</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1272-1280.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0014" target="_blank" class="mainColor">10.37188/CO.2024-0014</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0014" target="_blank" class="mainColor">32171.14.CO.2024-0014</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0014" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">208</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0014" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">112</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('1a3e8c4e-d0fd-446c-9add-d80d00d5c8f9');"><img src="/style/web/images/custom/icopdf.png" />PDF 4327KB</a>(<span class="colorRed pdf-num">75</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to adapt to the complex dynamic changing wake bubble field environment, improve the detection signal-to-noise ratio and detection rate of the weak ship wake signals, and expand the detection range, a method of detecting weak ship wake signals based on the synchronous accumulation method is proposed.

In order to evaluate the detection performance of the algorithm under multi-parameter coupling, a multi-time scale detection capability evaluation model for weak ship wake signals is established. By conducting many simulated ship wake detection experiments in large indoor pools and typical outdoor lakes, it is verified that the algorithm is suitable for the detection of various bubbles from smaller ones in sparse and discrete tiny far-field wakes to larger near-field ones under high turbulence disturbance, thus realizing full-time ship wake tracking and detection.

Aiming at the problems of weak features and background information interference of small targets in sonar images, we propose a weak feature confocal channel modulation algorithm for underwater sonar target detection. First, in order to improve the model's ability to capture and characterize the information of weak targets, we design a weak target-specific activation strategy and introduce an a priori frame scale calibration mechanism to match the underlying semantic feature detection branch to improve the accuracy of small target detection; second, we apply the global information aggregation module to deeply excavate the global features of weak targets to avoid the redundant information from covering the small target's weak key features; finally, in order to solve the problem of traditional spatial pyramid pooling which is easy to ignore the channel information, the confocal channel regulation pooling module is proposed to retain effective channel domain small target information and overcome interference from complex background information. Experiment results show that the model in this paper achieves an average detection accuracy of 83.3% on nine types of weak targets in the underwater sonar dataset, which is 5.5% higher than the benchmark. Among these, the detection accuracy of iron buckets, human body models and cubes is significantly improved by 24%, 8.6%, and 7.3%, respectively, effectively solving the problem of leakage and misdetection of weak targets in complex underwater environment.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="b2251013-66d1-4d4d-9090-8e8bf7c8ab68"> <div class="article-list-left"><input name="journalArticleCheck" value="b2251013-66d1-4d4d-9090-8e8bf7c8ab68" type="checkbox" checkArticleId="b2251013-66d1-4d4d-9090-8e8bf7c8ab68"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0008-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0008-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0008-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0008" class="" target="_blank">Sea surface glint suppression method based on polarization feature reconstruction</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","SONG Ming-zhu","");'>SONG Ming-zhu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," GUO Rong","");'> GUO Rong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Li-zhou","");'> LI Li-zhou</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," TAO Shu-ping","");'> TAO Shu-ping</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHEN Yan-tong","");'> CHEN Yan-tong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Jun-sheng","");'> WANG Jun-sheng</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1297-1306.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0008" target="_blank" class="mainColor">10.37188/CO.2024-0008</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0008" target="_blank" class="mainColor">32171.14.CO.2024-0008</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0008" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">206</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0008" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">167</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('b2251013-66d1-4d4d-9090-8e8bf7c8ab68');"><img src="/style/web/images/custom/icopdf.png" />PDF 5645KB</a>(<span class="colorRed pdf-num">79</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Sun glint is a significant factor influencing sea surface target detection. For land observation platforms, a sea surface glint suppression method based on the reconstruction of common and feature components of linearly polarized images is proposed using the polarization characteristics of glints. We use a focal plane polarization camera to obtain four-channel linear polarized images, calculate the scene’s polarization information, and generate a glint suppression image. Based on suppressing scene glint with polarization information combined with the characteristics of linear polarization images, the light intensity components of the glint suppression image are decomposed into common and characteristic components, and new weight factors are reassigned to obtain the reconstructed glint suppression image. The glint polarization imaging experiments show that in the three sets of typical experimental data, the proportion of saturated pixels in the reconstructed glint suppressed image is decreased by up 79.07%. Compared to the intensity image, and the spatial frequency and contrast are increased by up to 73.77% and 172.73%, respectively. The method proposed in this paper effectively suppresses the glint noise in the sea scene and performs well in restoring background detail information.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="8b340be8-bb4a-4ff0-8c9e-cffa6be55acb"> <div class="article-list-left"><input name="journalArticleCheck" value="8b340be8-bb4a-4ff0-8c9e-cffa6be55acb" type="checkbox" checkArticleId="8b340be8-bb4a-4ff0-8c9e-cffa6be55acb"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0193-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0193-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0193-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0193" class="" target="_blank">Remote-sensing image enhancement based on tensor decomposition and nonsubsampled Contourlet transform</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","WU Qing-ling","");'>WU Qing-ling</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SHI Qiang","");'> SHI Qiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," DU Yong-sheng","");'> DU Yong-sheng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LEI Sai","");'> LEI Sai</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LU Ming-ming","");'> LU Ming-ming</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1307-1315.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0193" target="_blank" class="mainColor">10.37188/CO.2024-0193</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0193" target="_blank" class="mainColor">32171.14.CO.2024-0193</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0193" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">109</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0193" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">34</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('8b340be8-bb4a-4ff0-8c9e-cffa6be55acb');"><img src="/style/web/images/custom/icopdf.png" />PDF 4898KB</a>(<span class="colorRed pdf-num">61</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In the process of remote sensing image acquisition, low quality and lack of important information of image are common problems as the existence of interference information. Traditional image enhancement methods often cannot highlight useful information with high precision and high efficiency because they cannot integrate global information effectively. In order to solve these problems, a remote-sensing image enhancement method based on tensor decomposition and nonsubsampled Contourlet transform is proposed. The optimized nonsubsampled Contourlet transform is used to decompose the original image, and the high-order tensor is composed of high-frequency detail images in all directions on all scales. Through Bayesian probability tensor completion, the potential factors recognized from the incomplete tensor are used to predict the missing details of the image. Experimental results indicate that the proposed method can recover the missing information more effectively and highlight the feature information of the image. Compared with different image enhancement methods, the maximum improvement of signal-to-noise ratio, structure similarity and root mean square error are 27.9%, 37.6% and 45.4%, respectively. The proposed method is superior to the common image enhancement methods in quantitative evaluation and visual comparison.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="878a20e1-e211-44a3-a077-543c3e186cf1"> <div class="article-list-left"><input name="journalArticleCheck" value="878a20e1-e211-44a3-a077-543c3e186cf1" type="checkbox" checkArticleId="878a20e1-e211-44a3-a077-543c3e186cf1"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0196-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0196-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2023-0196-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2023-0196" class="" target="_blank">Image reconstruction of snapshot multispectral camera based on an attention residual network</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","YAN Gang-qi","");'>YAN Gang-qi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIANG Zong-lin","");'> LIANG Zong-lin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SONG Yan-song","");'> SONG Yan-song</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," DONG Ke-yan","");'> DONG Ke-yan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Bo","");'> ZHANG Bo</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Tian-ci","");'> LIU Tian-ci</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Lei","");'> ZHANG Lei</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Yan-bo","");'> WANG Yan-bo</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1316-1328.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2023-0196" target="_blank" class="mainColor">10.37188/CO.2023-0196</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2023-0196" target="_blank" class="mainColor">32171.14.CO.2023-0196</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2023-0196" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">260</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2023-0196" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">81</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('878a20e1-e211-44a3-a077-543c3e186cf1');"><img src="/style/web/images/custom/icopdf.png" />PDF 5216KB</a>(<span class="colorRed pdf-num">85</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>With the rapid advancement of spectral imaging technology, the use of multispectral filter array (MSFA) to collect the spatial and spectral information of multispectral images has become a research hotspot. The uses of the original data are limited because of its low sampling rate and strong spectral inter-correlation for reconstruction. Therefore, we propose a multi-branch attention residual network model for spatial-spectral association based on an 8-band 4 × 4 MSFA with all-pass bands. First, the multi-branch model was used to learn the image features after interpolation in each band; second, the feature information of the eight bands and the all-pass band were united by the spatial channel attention model designed in this paper, and the application of multi-layer convolution and the convolutional attention module and the use of residual compensation effectively compensated the color difference of each band and enriched the edge texture-related feature information. Finally, the preliminary interpolated full-pass band and the rest of the band feature information were used for feature learning of the spatial and spectral correlations of multispectral images through residual dense blocks without batch normalization to match the spectral information of each band. Experimental results show that the peak signal-to-noise ratio, structural similarity, and spectral angular similarity of the test image under the D65 light source outperform the state-of-the-art deep learning method by 3.46%, 0.27%, and 6%, respectively.

Co-phase detection technology based on a broad-band light source solves the problem of long measurement times caused by the Shackle-Hartmann method’s low target flow rates, thereby improving the accuracy and range of piston error detection. However, in the application of the current broad-band algorithm, the complex environment and the presence of disturbing factors such as camera perturbations cause the acquired circular aperture diffraction images to contain a certain amount of noise, which leads to a correlation coefficient value below the set threshold, reduces the accuracy of the method, and even makes it ineffective. To solve the problem, we propose a method by integrating an algorithm based on Denoising Convolutional Neural Network (DnCNN) into the broad-band algorithm in order to control the noise interference and retain the phase information of the far-field image. First, the circular hole diffraction image obtained by using MATLAB is used as the training data for DnCNN. After the training, the images with different noise levels are imported into the trained noise reduction model to obtain the denoised image as well as the peak signal-to-noise ratios of the circular hole diffraction images before and after denoising. The structural similarity between the two images and the clear and noiseless image are also obtained. The results indicate that the average structural similarity between the denoised image and the ideal clear image has significantly improved compared to the image before processing, and this achieves an ideal denoising effect, which effectively increases the ability of broad-band algorithms to cope with the effects of high noise conditions. This study has strong theoretical significance and application value for exploring the broad-band light source algorithm for applications in practical co-phase detection environments.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="baf3ff62-6ccd-4be6-bbe6-f3d9a9406abd"> <div class="article-list-left"><input name="journalArticleCheck" value="baf3ff62-6ccd-4be6-bbe6-f3d9a9406abd" type="checkbox" checkArticleId="baf3ff62-6ccd-4be6-bbe6-f3d9a9406abd"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0071-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0071-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0071-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0071" class="" target="_blank">Research on high-precision gas concentration inversion based on adaptive infrared multi-band joint spectral analysis</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","WANG Guan-cheng","");'>WANG Guan-cheng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Bai-xuan","");'> ZHAO Bai-xuan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHENG Kai-feng","");'> ZHENG Kai-feng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CHEN Yu-peng","");'> CHEN Yu-peng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Ying-ze","");'> ZHAO Ying-ze</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," QIN Yu-xin","");'> QIN Yu-xin</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Wei-biao","");'> WANG Wei-biao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Guo-hao","");'> LIU Guo-hao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," SHENG Kai-yang","");'> SHENG Kai-yang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LV Jin-guang","");'> LV Jin-guang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIANG Jing-qiu","");'> LIANG Jing-qiu</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1340-1350.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0071" target="_blank" class="mainColor">10.37188/CO.2024-0071</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0071" target="_blank" class="mainColor">32171.14.CO.2024-0071</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0071" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">285</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0071" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">72</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('baf3ff62-6ccd-4be6-bbe6-f3d9a9406abd');"><img src="/style/web/images/custom/icopdf.png" />PDF 1372KB</a>(<span class="colorRed pdf-num">98</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In this paper, we proposed an adaptive multi-band joint concentration inversion algorithm, which combines the transmittance stable range and the spectral width threshold to adaptively select the effective band of the measured gas.

The electric field strength is a critical parameter understanding the characteristics of electron beams. The laser-induced fluorescence-dip spectroscopy method based on the Stark effect can realize the tiny perturbation measurement of electric fields. Therefore, Studying laser power density influence on the electric field has significant theoretical and application value for the parameter setting and result interpretation of similar electric field measurement methods. The theoretical analysis and calculation are used to obtain the relationship model between excitation laser power density and the test environment parameters in the tiny perturbation state of electric field measurement. Then, based on the above relationship model and theoretical calculation, the influence of excitation laser power density on electric field measurement is verified experimentally. The experimental results show that under the conditions that the tracer gas xenon pressure is 1.0×10<sup>−4</sup> mbar and the electric field strength is 2 kV/cm or below, the excitation laser power density of tiny perturbations on the electric field measurement is 5 MW/cm<sup>2</sup>, which is consistent with the theoretical calculation value. The research results provide a quantitative analysis method for studying the influence of laser power density on the electric field in the laser-induced fluorescence-dip spectroscopy. They can be applied to similar electric field measurement methods, open the way for the setting of laser power density and experimental parameters, support the development of electric field measurement experiments, and effectively improve the accuracy of electric field measurement.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="370093b9-eebb-4c3c-a031-355d69b29840"> <div class="article-list-left"><input name="journalArticleCheck" value="370093b9-eebb-4c3c-a031-355d69b29840" type="checkbox" checkArticleId="370093b9-eebb-4c3c-a031-355d69b29840"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0076-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0076-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2023-0076-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2023-0076" class="" target="_blank">Rapid wide dynamic non-uniformity correction algorithm for infrared radiation measurement system</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","LI Zhou","");'>LI Zhou</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Yao-yu","");'> ZHANG Yao-yu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHOU Hui","");'> ZHOU Hui</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," KONG Xiang-long","");'> KONG Xiang-long</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Xin-yu","");'> ZHAO Xin-yu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Xiang-chen","");'> LI Xiang-chen</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1359-1367.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2023-0076" target="_blank" class="mainColor">10.37188/CO.2023-0076</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2023-0076" target="_blank" class="mainColor">32171.14.CO.2023-0076</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2023-0076" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">110</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2023-0076" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">134</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('370093b9-eebb-4c3c-a031-355d69b29840');"><img src="/style/web/images/custom/icopdf.png" />PDF 4639KB</a>(<span class="colorRed pdf-num">63</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In this paper, a rapid and wide dynamic non-uniformity correction algorithm is proposed for the requirement of continuous change of integration time in infrared radiation measurement system.

The experimental verification was conducted by employing cooled mid-wave infrared radiation characteristic measurement system with a 25 mm aperture. The correction efficiency of the classical algorithm and the proposed algorithm are compared. The results indicate that the proposed algorithm is 3.4 times more efficient than the traditional non-uniformity correction algorithm. On the above basis, we evaluate the effect of the two algorithms on the image correction using residual non-uniformity. Multiple integration times (0.6 ms, 3 ms and 3.5 ms) are used to simulate the continuous change of integration.

Initially, the pupil alignment device was constructed on a laboratory fundus imaging system using a visible light camera module and a three-dimensional electric displacement stage. Subsequently, the effective area of the image was extracted using the Hough gradient method to determine the center of the fundus imaging system. The pupil region was identified through the maximum inter-class variance method and image histogram feature, while the center of the pupil was ascertained via the minimum circle fitting method. Ultimately, the electric displacement stage's movement is regulated through feedback mechanisms, ensuring that the center of the fundus imaging system aligns precisely with the pupil's center. The experimental results show that the average recognition speed of human pupil is 0.11 s, the average recognition accuracy of the pupil center is 98.7%, and the average Euclidean distance of the center deviation is 4.3 pixels. It can satisfy the system requirements of the real-time and accuracy, and provides an efficient automatic pupil alignment solution for fundus imaging system.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="77b9d3dd-73bc-48c0-9b4c-c6708eb2e627"> <div class="article-list-left"><input name="journalArticleCheck" value="77b9d3dd-73bc-48c0-9b4c-c6708eb2e627" type="checkbox" checkArticleId="77b9d3dd-73bc-48c0-9b4c-c6708eb2e627"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0034-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0034-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0034-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0034" class="" target="_blank">Non-contact blood oxygen saturation measurement in dynamic head scenes</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","LIU Tao","");'>LIU Tao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Ya-li","");'> ZHANG Ya-li</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1377-1386.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0034" target="_blank" class="mainColor">10.37188/CO.2024-0034</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0034" target="_blank" class="mainColor">32171.14.CO.2024-0034</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0034" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">340</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0034" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">101</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('77b9d3dd-73bc-48c0-9b4c-c6708eb2e627');"><img src="/style/web/images/custom/icopdf.png" />PDF 3915KB</a>(<span class="colorRed pdf-num">65</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In dynamic head scenes, current non-contact blood oxygen saturation measurement methods have low accuracy. To solve this problem, we propose a denoising method based on improved adaptive noise complete set empirical mode decomposition and wavelet threshold. This method aims to extract pulse wave signals with a high signal-to-noise ratio. Firstly, in order to solve the problem of false components and mode aliasing in the early stage of decomposition and reconstruction, white Gaussian noise is added to the decomposition process to make it become an improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN), to reduce the residual noise in the modal components. Then, ICEEMDAN is used to perform mode decomposition of pulse wave signals of red and blue channels. The db8 wavelet basis function is used to perform 3-stage decomposition and reconstruction on components within the blood oxygen spectrum range. The reconstructed signals are used for subsequent calculation of blood oxygen value. Finally, the experimental comparison and analysis of the blood oxygen saturation results measured in different dynamic head scenes show that the average error of blood oxygen saturation obtained in different head scenes is 0.73%, which is 1.93% lower than the average error of other algorithms. The denoising method proposed in this paper has good stability in different head scenes and can meet the needs of daily blood oxygen saturation measurement.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="13c71151-7e28-4318-a863-48acd7ce3e9e"> <div class="article-list-left"><input name="journalArticleCheck" value="13c71151-7e28-4318-a863-48acd7ce3e9e" type="checkbox" checkArticleId="13c71151-7e28-4318-a863-48acd7ce3e9e"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0041-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0041-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0041-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0041" class="" target="_blank">Tilt error’s characteristic analysis of dual liquid crystal polarization grating system</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","FANG Yuan-xiang","");'>FANG Yuan-xiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIANG Lun","");'> JIANG Lun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," PEI Hui-yi","");'> PEI Hui-yi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Jin-jiang","");'> WANG Jin-jiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CUI Yong","");'> CUI Yong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Jia-ming","");'> ZHANG Jia-ming</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1387-1396.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0041" target="_blank" class="mainColor">10.37188/CO.2024-0041</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0041" target="_blank" class="mainColor">32171.14.CO.2024-0041</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0041" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">162</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0041" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">110</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('13c71151-7e28-4318-a863-48acd7ce3e9e');"><img src="/style/web/images/custom/icopdf.png" />PDF 1993KB</a>(<span class="colorRed pdf-num">57</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to precisely control the direction of laser beams, we analyze the error caused by the grating tilt in the system based on the optical beam pointing algorithm of the dual liquid crystal polarization grating system. Firstly, a ray tracing method based on the diffraction grating equation is used to solve the outgoing beam pointing, introducing the incident beam pointing and grating tilt angle. The correctness and accuracy of this method are verified through comparison with simulation results. Secondly, by analyzing different cases of grating tilt, we provide expressions of the grating attitude under different tilt conditions, and in combination with the ray tracing method, obtain the expressions for the outgoing beam pointing for corresponding situations, analyzing the zeroing error and rotation error caused by grating tilt. The research results indicate that within the 0° to 0.3° grating tilt angle range, the zeroing errors are within 0.25 mrad and 2 mrad respectively, and the rotation errors are around 85 mrad and 430 mrad, respectively. We propose a method for accurately calculating the pointing direction and grating tilt errors in the exit beam of a dual liquid crystal polarization grating system.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="5f1b4681-dc01-4058-b3df-e30e87538ba8"> <div class="article-list-left"><input name="journalArticleCheck" value="5f1b4681-dc01-4058-b3df-e30e87538ba8" type="checkbox" checkArticleId="5f1b4681-dc01-4058-b3df-e30e87538ba8"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0049-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0049-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0049-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0049" class="" target="_blank">Design of an angle measurement system based on interferometric fringe imaging and its off-axis measurement accuracy</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","SONG Ying","");'>SONG Ying</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LIU Yu-juan","");'> LIU Yu-juan</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1397-1407.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0049" target="_blank" class="mainColor">10.37188/CO.2024-0049</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0049" target="_blank" class="mainColor">32171.14.CO.2024-0049</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0049" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">145</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0049" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">104</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('5f1b4681-dc01-4058-b3df-e30e87538ba8');"><img src="/style/web/images/custom/icopdf.png" />PDF 2240KB</a>(<span class="colorRed pdf-num">67</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>The accuracy of an angle measurement system based on interferometric fringe imaging decreases as the measurement range increases. Merely increasing the subdivision factor of precise positioning cannot improve the accuracy of the measurement. In this case, this paper primarily focuses on the parameter design method in non-imaging optical systems and accuracy changes under a wide measurement range. The mathematical models for the dual grating interference system and the wavefront segmentation of the optical wedge array were established, and a parameter design method for non-imaging optical systems under paraxial conditions was proposed. A one-dimensional high-precision angle measurement system was designed, and the measurement error of the system within the measurement range was analyzed and calculated. The results show that the designed angle measurement system achieves a resolution of 0.02" in the paraxial region with a measurement range of [−5°,5°] based on the mathematical model and method proposed in this paper. As the measurement range expands, the precision positioning errors resulting from nonlinear changes in the phase of interference fringes become the primary source of measurement errors. At the maximum measurement angle, the accuracy of the precision axis reduces to 0.42". The above results demonstrate that the proposed model and parameter design method can be employed to design an optical angle measurement system with high accuracy.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="e150e563-63c2-4404-8989-03c5075f85bf"> <div class="article-list-left"><input name="journalArticleCheck" value="e150e563-63c2-4404-8989-03c5075f85bf" type="checkbox" checkArticleId="e150e563-63c2-4404-8989-03c5075f85bf"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0010-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0010-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0010-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0010" class="" target="_blank">Polarization aberration analysis of catadioptric anamorphic optical systems and its effect on the point spread function</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","MA Shi-jie","");'>MA Shi-jie</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WU Hong-bo","");'> WU Hong-bo</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Shang-nan","");'> ZHAO Shang-nan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WU Qing","");'> WU Qing</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Xin","");'> ZHANG Xin</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1408-1417.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0010" target="_blank" class="mainColor">10.37188/CO.2024-0010</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0010" target="_blank" class="mainColor">32171.14.CO.2024-0010</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0010" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">286</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0010" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">117</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('e150e563-63c2-4404-8989-03c5075f85bf');"><img src="/style/web/images/custom/icopdf.png" />PDF 2764KB</a>(<span class="colorRed pdf-num">80</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>The anamorphic optical system is a relatively special optical system with bi-planar symmetry, whose structure gives rise to non-rotationally symmetric polarization aberrations. Aiming at the problem, we construct a catadioptric anamorphic optical system. Furthermore, we also systematically analyzes the polarization aberration of this system and its effect on the point spread function. Simulations of a catadioptric anamorphic optical system based on a three-dimensional polarized light trace are performed to obtain detailed data on the polarization aberration and to compute the diattenuation and retardance distribution characteristics of individual surfaces, as well as the Jones pupil, the amplitude response matrix, the point spread function, and the polarization crosstalk contrast of the system. The maximum diattenuation is 0.145, and the maximum retardance is 1.46×10<sup>−2</sup> rad, both occurring at the secondary mirror position. The amplitude response function of the optical system with a 2∶1 anamorphic ratio has a 40.6% difference between the polarization crosstalk term in the long and short focal end directions, and the anamorphic optical systems contrast is limited by an order of magnitude of 10<sup>−6</sup> by polarization crosstalk. Polarization aberration in high-precision anamorphic optical systems is not negligible. The effects of polarization aberration can be reduced by film layer design and catadioptric structure. The conclusions of this study can serve as a reference for designing anamorphic optical systems in deep space exploration and coherent communication systems.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="b63d3ef7-5264-4e03-835f-72bcd949451e"> <div class="article-list-left"><input name="journalArticleCheck" value="b63d3ef7-5264-4e03-835f-72bcd949451e" type="checkbox" checkArticleId="b63d3ef7-5264-4e03-835f-72bcd949451e"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0206-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0206-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2023-0206-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2023-0206" class="" target="_blank">Design of a fast multi-dimensional imaging guidance optical system based on array optics</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","SHI Hao-dong","");'>SHI Hao-dong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LU Qi","");'> LU Qi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Yi-wu","");'> ZHAO Yi-wu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," WANG Jia-yu","");'> WANG Jia-yu</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHAO Xiao","");'> ZHAO Xiao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," LI Ying-chao","");'> LI Ying-chao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," FU Qiang","");'> FU Qiang</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1418-1430.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2023-0206" target="_blank" class="mainColor">10.37188/CO.2023-0206</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2023-0206" target="_blank" class="mainColor">32171.14.CO.2023-0206</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2023-0206" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">240</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2023-0206" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">124</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('b63d3ef7-5264-4e03-835f-72bcd949451e');"><img src="/style/web/images/custom/icopdf.png" />PDF 5250KB</a>(<span class="colorRed pdf-num">100</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>To address the bottleneck that makes the conventional polarization spectral imaging method difficult to apply to the ballistic platform, a fast multi-dimensional imaging guidance optical system based on array optics is proposed. The correlation model between channel resolution and telescopic magnification is constructed. The precise matching and efficient utilization of the parameters of the microlens array, spectral filter array, and micro-nano-polarization array detector are realized. Based on the conventional guidance head and commercial polarization detector, a multi-dimensional imaging guidance optical system with spherical dome is designed. The system adopts a 4×4 optical field segmentation layout, forming 16 spectral channels through the visible light band with a spectral resolution of 16 nm. A polarization spectral data cube in four polarization directions, such as 0°, 45°, 90°, and 135° is acquired efficiently under the conditions of a single optical path and a single detector. The system has an effective focal length of 150 mm and a structure length of 145 mm. Simulation results show that the full-field modulation transfer function of the system is close to the diffraction limit at the Nyquist frequency for 16 channels. The imaging quality meets the requirements of bullet-loaded target multi-dimensional detection and identification.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="a123dbbd-efc1-4777-8e61-7c8fa6c934c5"> <div class="article-list-left"><input name="journalArticleCheck" value="a123dbbd-efc1-4777-8e61-7c8fa6c934c5" type="checkbox" checkArticleId="a123dbbd-efc1-4777-8e61-7c8fa6c934c5"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0007-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0007-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0007-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0007" class="" target="_blank">Design of cooled infrared dual-band zoom optical system with large-magnification-ratio</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","GENG Hai-tao","");'>GENG Hai-tao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YU Lin-yao","");'> YU Lin-yao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Bao","");'> ZHANG Bao</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1431-1441.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0007" target="_blank" class="mainColor">10.37188/CO.2024-0007</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0007" target="_blank" class="mainColor">32171.14.CO.2024-0007</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0007" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">227</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0007" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">135</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('a123dbbd-efc1-4777-8e61-7c8fa6c934c5');"><img src="/style/web/images/custom/icopdf.png" />PDF 4728KB</a>(<span class="colorRed pdf-num">87</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>The development of third-generation infrared focal plane detectors allows them to respond simultaneously to two different bands of infrared radiation, and the dual-band image brings significant benefits to target detection and identification. In this paper, a cooled infrared dual-band zoom optical system with large-magnification-ratio is designed for aerial detection applications. The system includes a 320×256 dual-color infrared-cooled detector. It operates in the bands of 3.7−4.8 μm in mid-wave and 7.7−9.5 μm in long-wave. The optical system adopts the combination of refractive and catadioptric structures to realize an optical four-field-of-view switching wide-range zoom. In order to realize the 100% cold diaphragm efficiency, a secondary imaging mode is adopted. The four-field-of-view focal lengths of the optical system are 32 mm, 200 mm, 800 mm, and <styled-content style-type="number">1600</styled-content> mm, and the zoom ratio is 50×. The experimental results show that the optical system is close to the diffraction limit at a modulation transfer function eigenfrequency of 17 lp/mm in each dual-band zoom state. The optical system has dual-band characteristics, extensive zoom ratio and large range, fast switching of multiple fields of view, simple and compact structure, and high-quality imaging, which will be useful in a wide range of security fields such as searching, reconnaissance, and so on.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="a594c239-faac-4e59-a185-c450c8b1d496"> <div class="article-list-left"><input name="journalArticleCheck" value="a594c239-faac-4e59-a185-c450c8b1d496" type="checkbox" checkArticleId="a594c239-faac-4e59-a185-c450c8b1d496"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0015-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2024-0015-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2024-0015-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2024-0015" class="" target="_blank">Development of phase delay mirrors for femtosecond laser systems</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","NIU Hong-kun","");'>NIU Hong-kun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," ZHANG Jing","");'> ZHANG Jing</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," FU Xiu-hua","");'> FU Xiu-hua</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," MA Guo-shui","");'> MA Guo-shui</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIN Hai-jun","");'> JIN Hai-jun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YANG Fei","");'> YANG Fei</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1442-1449.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2024-0015" target="_blank" class="mainColor">10.37188/CO.2024-0015</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2024-0015" target="_blank" class="mainColor">32171.14.CO.2024-0015</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2024-0015" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">237</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2024-0015" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">115</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('a594c239-faac-4e59-a185-c450c8b1d496');"><img src="/style/web/images/custom/icopdf.png" />PDF 3987KB</a>(<span class="colorRed pdf-num">69</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Phase delay mirrors were designed and prepared to regulate femtosecond laser systems’ group-delay dispersion (GDD).

However, the direct use of fiber arrays leads to discontinuity of the imaging field-of-view and causes the focal length of the subaperture to lengthen, and the thickness is increased substantially. To address the above problems, we propose a combination of microlens arrays and fiber optic arrays to subdivide the subaperture image plane to achieve a seamless splicing of the field-of-view, and to significantly reduces the overall thickness of the subaperture array through the combination of the telephoto objective lens and the three-lens spatial compression plate. The design results show that by adding 65×65 microlens array in front of the fiber array to focus the beam twice to achieve the system field of view seamless splicing, the field of view is expanded 65 times, the full field of view is <styled-content style-type="number">0.0489</styled-content>°, the efficiency of spatial optical coupling in the center of each fiber in the single-mode fiber array is not less than 40% when the visible light is incident, and after adding the spatial compression plate to compress the free-space light path, the overall thickness of the system achieves one order of magnitude compression. This design realizes photonic integrated interference imaging system large field of view seamless splicing imaging at the same time, provides a new way for the solution of the problem of excessive thickness in ultra-long focal length lenses.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="405fca43-b95f-46a8-95d4-c9062ac781ce"> <div class="article-list-left"><input name="journalArticleCheck" value="405fca43-b95f-46a8-95d4-c9062ac781ce" type="checkbox" checkArticleId="405fca43-b95f-46a8-95d4-c9062ac781ce"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-EN-2024-0017-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-EN-2024-0017-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-EN-2024-0017-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN-2024-0017" class="" target="_blank">Witnessing quantum phase transition in a non-Hermitian trapped ion system via quantum Fisher information</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","LIN Yu-Hao","");'>LIN Yu-Hao</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," YAN Kai","");'> YAN Kai</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," TAN Jia","");'> TAN Jia</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CAO Zhao-Liang","");'> CAO Zhao-Liang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," HAO Xiang","");'> HAO Xiang</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1467-1475.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.EN-2024-0017" target="_blank" class="mainColor">10.37188/CO.EN-2024-0017</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.EN-2024-0017" target="_blank" class="mainColor">32171.14.CO.EN-2024-0017</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0017" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">222</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0017" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">101</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('405fca43-b95f-46a8-95d4-c9062ac781ce');"><img src="/style/web/images/custom/icopdf.png" />PDF 1377KB</a>(<span class="colorRed pdf-num">69</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>Quantum Fisher information is used to witness the quantum phase transition in a non-Hermitian trapped ion system with balanced gain and loss, from the viewpoint of quantum parameter estimation. We formulate a general non-unitary dynamic of any two-level non-Hermitian system in the form of state vector. The sudden change in the dynamics of quantum Fisher information occurs at an exceptional point characterizing quantum criticality. The dynamical behaviors of quantum Fisher information are classified into two different ways which depends on whether the system is located in symmetry unbroken or broken phase regimes. In the phase regime where parity and time reversal symmetry are unbroken, the oscillatory evolution of quantum Fisher information is presented, achieving better quantum measurement precision. In the broken phase regime, quantum Fisher information undergoes the monotonically decreasing behavior. The maximum value of quantum estimation precision is obtained at the exceptional point. It is found that the two distinct kinds of behaviors can be verified by quantum entropy and coherence. Utilizing quantum Fisher information to witness phase transition in the non-Hermitian system is emphasized.

Mitigating SEE on metal surfaces is crucial for enhancing the stability and emittance of particle accelerators while extending their lifespan. This paper explores the application of laser-assisted water jet technology in constructing high-quality micro-trap structures on 316L stainless steel, a key material in accelerator manufacturing. The study systematically analyzes the impact of various parameters such as laser repetition frequency, pulse duration, average power, water jet pressure, repeat times, nozzle offset, focal position, offset distance between grooves, and processing speed on the surface morphology of stainless steel. The findings reveal that micro-groove depth increases with higher laser power but decreases with increasing water jet pressure and processing speed. Interestingly, repeat times have minimal effect on depth. On the other hand, micro-groove width increases with higher laser power and repeat times but decreases with processing speed. By optimizing these parameters, the researchers achieved high-quality pound sign-shaped trap structure with consistent dimensions. We tested the secondary electron emission coefficient of the "well" structure. The coefficient is reduced by 0.5 at most compared to before processing, effectively suppressing secondary electron emission. These results offer indispensable insights for the fabrication of micro-trap structures on material surfaces. Laser-assisted water jet technology demonstrates considerable potential in mitigating SEE on metal surfaces.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="187f79c9-c348-4670-8bbb-59acfc890573"> <div class="article-list-left"><input name="journalArticleCheck" value="187f79c9-c348-4670-8bbb-59acfc890573" type="checkbox" checkArticleId="187f79c9-c348-4670-8bbb-59acfc890573"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0234-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-2023-0234-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-2023-0234-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2023-0234" class="" target="_blank">Opto-mechanical-thermal integration analysis of Doppler asymmetric spatial heterodyne interferometer</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","WANG Jin-jiang","");'>WANG Jin-jiang</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," JIANG Lun","");'> JIANG Lun</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," TONG Shou-feng","");'> TONG Shou-feng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," PEI Hui-yi","");'> PEI Hui-yi</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," CUI Yong","");'> CUI Yong</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," GUO Ming-hang","");'> GUO Ming-hang</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1489-1511.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.2023-0234" target="_blank" class="mainColor">10.37188/CO.2023-0234</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2023-0234" target="_blank" class="mainColor">32171.14.CO.2023-0234</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2023-0234" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">242</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2023-0234" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">96</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('187f79c9-c348-4670-8bbb-59acfc890573');"><img src="/style/web/images/custom/icopdf.png" />PDF 7193KB</a>(<span class="colorRed pdf-num">93</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to improve the detection accuracy of Doppler asymmetric spatial heterodyne (DASH) interferometer in harsh temperatures, an opto-mechanical-thermal integration analysis is carried out. Firstly, the correlation between the interference phase and temperature is established according to the working principle and the phase algorithm of the interferometer. Secondly, the optical mechanical thermal analysis model and thermal deformation data acquisition model are designed. The deformation data of the interference module and the imaging optical system at different temperatures are given by temperature load simulation analysis, and the phase error caused by thermal deformation is obtained by fitting. Finally, based on the wind speed error caused by thermal deformation of each component, a reasonable temperature control scheme is proposed. The results show that the interference module occupies the main cause, the temperature must be controlled within (20±0.05) °C, and the temperature control should be carried out for the temperature sensitive parts, and the wind speed error caused by the part is 3.8 m/s. The thermal drift between the magnification of the imaging optical system and the thermal drift of the relative position between the imaging optical system and the detector should occupy the secondary cause, which should be controlled within (20±2) °C, and the wind speed error caused by the part is 3.05 m/s. In summary, the wind measurement error caused by interference module, imaging optical system, and the relative position between the imaging optical system and the detector can be controlled within 6.85 m/s. The analysis and temperature control schemes presented in this paper can provide theoretical basis for DASH interferometer engineering applications.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> <div class="article-list" id="9cbe3601-4417-4753-aab9-1a65062ce33f"> <div class="article-list-left"><input name="journalArticleCheck" value="9cbe3601-4417-4753-aab9-1a65062ce33f" type="checkbox" checkArticleId="9cbe3601-4417-4753-aab9-1a65062ce33f"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/6/CO-EN-2024-0003-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/6/CO-EN-2024-0003-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/6/CO-EN-2024-0003-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.EN-2024-0003" class="" target="_blank">Influence of sampling on three-dimensional surface shape measurement</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","QIAO Nao-sheng","");'>QIAO Nao-sheng</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," Shang Xue","");'> Shang Xue</a> </span> </div> <div class="article-list-time"> <font>2024, 17(6): 1512-1520.</font>   <font> doi: <a href="http://dx.doi.org/10.37188/CO.EN-2024-0003" target="_blank" class="mainColor">10.37188/CO.EN-2024-0003</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.EN-2024-0003" target="_blank" class="mainColor">32171.14.CO.EN-2024-0003</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0003" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">146</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.EN-2024-0003" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">59</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('9cbe3601-4417-4753-aab9-1a65062ce33f');"><img src="/style/web/images/custom/icopdf.png" />PDF 2624KB</a>(<span class="colorRed pdf-num">65</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>In order to accurately measure an object’s three-dimensional surface shape, the influence of sampling on it was studied. First, on the basis of deriving spectra expressions through the Fourier transform, the generation of CCD pixels was analyzed, and its expression was given. Then, based on the discrete expression of deformation fringes obtained after sampling, its Fourier spectrum expression was derived, resulting in an infinitely repeated "spectra island" in the frequency domain. Finally, on the basis of using a low-pass filter to remove high-order harmonic components and retaining only one fundamental frequency component, the inverse Fourier transform was used to reconstruct the signal strength. A method of reducing the sampling interval, i.e., reducing the number of sampling points per fringe, was proposed to increase the ratio <inline-formula><tex-math id="M1">\begin{document}$ m $\end{document}</tex-math><alternatives><graphic specific-use="online" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="CO-EN-2024-0003_M1.jpg"/><graphic specific-use="print" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="CO-EN-2024-0003_M1.png"/></alternatives></inline-formula> between the sampling frequency and the fundamental frequency of the grating. This was done to reconstruct the object’s surface shape more accurately under the condition of <inline-formula><tex-math id="M2">\begin{document}$m > 4$\end{document}</tex-math><alternatives><graphic specific-use="online" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="CO-EN-2024-0003_M2.jpg"/><graphic specific-use="print" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="CO-EN-2024-0003_M2.png"/></alternatives></inline-formula>. The basic principle was verified through simulation and experiment. In the simulation, the sampling intervals were 8 pixels, 4 pixels, 2 pixels, and 1 pixel, the maximum absolute error values obtained in the last three situations were 88.80%, 38.38%, and 31.50% in the first situation, respectively, and the corresponding average absolute error values are 71.84%, 43.27%, and 32.26%. It is demonstrated that the smaller the sampling interval, the better the recovery effect. Taking the same four sampling intervals in the experiment as in the simulation can also lead to the same conclusions. The simulated and experimental results show that reducing the sampling interval can improve the accuracy of object surface shape measurement and achieve better reconstruction results.</p></span> <span class="extraAbstract"></span> </div>   <div style="display: none;" class="citation"> </div> </div> </div> </div> </div> </div> </div>   <div class="tab-pane fade articleListBox" id="category">  <div>  <div class="toolBoxBorder"> <div class="toolBox1 clearfix"> </div> <div class="toolBox2 clearfix"> </div> </div> <div class="article-list" id="d6fd7cc8-02ab-43d5-935e-d25a5a2683d9"> <div class="article-list-left"><input name="journalArticleCheck" value="d6fd7cc8-02ab-43d5-935e-d25a5a2683d9" type="checkbox" checkArticleId="d6fd7cc8-02ab-43d5-935e-d25a5a2683d9"></div> <div class="allwrap clearfix"> <div class="listpic fl"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/3/CO-2023-0156-1.jpg"> <img src="/fileZGGX/journal/article/zggx/2024/3/CO-2023-0156-1.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/3/CO-2023-0156-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1"/> </a> </div> <div class="listwrap"> <div class="article-list-right"> <div class="article-list-title"> <a href="/en/article/doi/10.37188/CO.2023-0156" class="" target="_blank">Advances in data simulation for space-based situational awareness</a> </div> <div class="article-list-author"> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn","LUO Xiu-juan","");'>LUO Xiu-juan</a>, </span> <span> <a href='javascript:void(0);' onclick='searchLike("authorNameEn"," HAO Wei","");'> HAO Wei</a> </span> </div> <div class="article-list-time"> <font>2024, 17(3): 501-511.</font>   <font> doi: <a href="https://doi.org/10.37188/CO.2023-0156" target="_blank" class="mainColor">10.37188/CO.2023-0156</a> </font> <div> cstr: <a href="https://cstr.cn/32171.14.CO.2023-0156" target="_blank" class="mainColor">32171.14.CO.2023-0156</a> </div> </div> <div class="article-list-zy clear"> <font class="font1"> <a href="/en/article/doi/10.37188/CO.2023-0156" target="_blank"><img src="/style/web/images/custom/icozy.png" />Abstract</a>(<span class="colorRed abs-num">723</span>) </font> <font class="font2 count1"> <a href="/en/article/doi/10.37188/CO.2023-0156" target="_blank"><img src="/style/web/images/custom/icohtm.png" />FullText HTML</a>(<span class="colorRed html-num">288</span>) </font> <font class="font3"> <a href="javascript:void(0);" onclick="downloadpdf('d6fd7cc8-02ab-43d5-935e-d25a5a2683d9');"><img src="/style/web/images/custom/icopdf.png" />PDF 0KB</a>(<span class="colorRed pdf-num">219</span>) </font> </div> <div class="article-list-zy morenstyle"> <b>Abstract: </b><br/> <span class="search-article-abstract" keep_len="250"><p>The data simulation for Space Situational Awareness (SSA) can provide critical data support for the development, testing, and validation of space surveillance equipment and situational awareness algorithms (including detection, tracking, recognition, and characterization of space object), playing a significant role in building SSA capabilities.

However, the accuracy of structured light for on-machine detection is compromised by the convoluted lighting in machining environments and metal parts’ high reflectivity, leading to inaccurate measurements. Applying high dynamic range (HDR) technology to structured light detection can reduce the effect of high reflectivity, achieving the measurement of metal parts in complex scenes. This paper introduces the measurement principle of structured light and summarizes the challenges of on-machine detection for HDR structured light. Subsequently, this paper provides a comprehensive review of HDR structured light technology. In the context of on-machine detection of mechanical processing, the HDR technology based on hardware equipment and the HDR technology based on stripe algorithm are discussed and analyzed, respectively. Following this, different technologies are summarized according to the requirements of on-machine detection. The advantages and disadvantages of various methods are presented, and the applicability of on-machine detection is compared. Finally, the potential applications are analyzed, and the technological prospects will be proposed in combination with the research hotspots of advanced manufacturing technology and precision measurement in recent years.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/1/CO-2023-0068-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2024/1/CO-2023-0068-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/1/CO-2023-0068-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

We review the physical mechanisms of LIBS technology in the current state, including the basic principles of LIBS, the differences in laser parameters, and the physical mechanisms involved in the differences in environmental and material properties.

Additionally, they are considered ideal sub-modules for high-power spectral combinations. The time domain of this type of seed is unstable due to the self-pulse effect, causing significant spectral broadening and stimulated Raman scattering effects during the amplification process, which limits their further improvement in output power and affects the purity of laser spectra. In this paper, we introduce four commonly used narrow linewidth seeds. The mechanism and suppression methods of the self-pulse effect in multi-longitudinal mode oscillator seeds are analyzed. Critical technologies essential for the optimization and relevant progress of the multi-longitudinal-mode oscillator seed source and amplifier stages are discussed in detail. A future development outlook is also presented. This paper serves as a useful reference for the design of narrow linewidth fiber lasers based on the multi-longitudinal-mode oscillator seed source.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2024/1/CO-2023-0074-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2024/1/CO-2023-0074-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2024/1/CO-2023-0074-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

In recent years, there has been a proliferation of optical path absorption spectroscopy techniques based on different light source technologies, absorption cavity technologies, and detection methods. As the demands on detection sensitivity and absorption optical path length increased, optical path absorption spectroscopy techniques based on the principle of enhanced absorption emerged, including integrated cavity spectroscopy (ICOS), cavity-enhanced absorption spectroscopy (CEAS) and cavity ring-down spectroscopy (CRDS). Enhanced absorption spectroscopy is advantageous for its high spectral resolution, high sensitivity, fast response time, and portability, but it presently lacks a unified concept and clear classification criteria. This paper compares the development history of absorption spectroscopy techniques and clarifies the concept of their multi-optical path. Based on whether resonant absorption occurs in the absorption cavity, the concept of absorption spectroscopy techniques based on resonance is proposed, and the current research status of resonant absorption spectroscopy techniques is analyzed and summarized, and the applications of this technique in various fields are outlined. Finally, the future development of key technologies in resonance absorption spectroscopy is envisioned.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/6/CO-2022-0246-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/6/CO-2022-0246-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/6/CO-2022-0246-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

The hetero-core structure of the optical fiber probe possesses inherent advantages in near-field evanescent wave optical trapping force, core beam coupling transmission, and cross-synergistic application of microfluidic technology, which can realize the functions of cell and subcellular particle collection and transportation, and can significantly improve the three-dimensional particle trapping capability as well as dynamic manipulation level. In this paper, the structural characteristics and application technology research progress of optical fiber tweezers based on different core structures are reviewed. This paper sorts and compares key technologies, including probe preparation, laser source, and coupling mode, in hetero-core optical fiber tweezers systems. It also summarizes and provides a perspective on the role and development of hetero-core fibers with different structures in optical fiber tweezers.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/6/CO-2023-0016-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/6/CO-2023-0016-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/6/CO-2023-0016-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

Nonetheless, their low External Quantum Efficiency (EQE) currently impedes their scaled mass production and further applications. In order to break through the bottleneck of low EQE, we conducted an analysis of Micro-LED external quantum efficiency’s contributing factors. The influencing factors for EQE are analyzed. It is concluded that the carrier loss and non-radiative recombination caused by sidewall defects are the main reasons for the decrease in EQE. In addition, we summarized the impact of sidewall defects on carrier transport and composites, and we also reviewed the commonly used sidewall treatment technology and repair methods, and pointed out that the existing sidewall treatment methods are helpful but insufficient for improving EQE, and the mechanism of carrier interaction with sidewall defects is not very clear. It is suggested to carry out a thorough and systematic study on the types and distribution of sidewall defects, the mechanism of carrier and sidewall defects, and the defect repair mode in the sidewall treatment process. Finally, future development trends are projected. This paper offers design ideas and theoretical foundations to enhance the external quantum efficiency and accelerate the process of commercialization and mass production of Micro-LEDs.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/6/CO-2023-0091-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/6/CO-2023-0091-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/6/CO-2023-0091-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

For specific application scenarios, polarization imaging has the excellent ability to distinguish different objects and highlight their outlines. Therefore, polarization imaging has been widely applied in the fields of object detection, underwater imaging, life science, environmental monitoring, 3D imaging, etc. Polarization splitting or the filtering device is the core element in a polarization imaging system. The traditional counterpart suffers from a bulky size, poor optical performance, and being sensitive to external disturbances, and can hardly meet the requirements of a highly integrated, highly functional, and highly stable polarization imaging system. A metasurface is a two-dimensional planar photonic device whose comprising units are arranged quasi-periodically at subwavelength intervals, and can finely regulate the amplitude and phase of the light field in different polarization directions. Polarization devices based on metasurface are featured with compactness, lightweight and multi-degree freedom, offering an original solution to ultracompact polarization imaging systems. Targeted at the field of polarization imaging, this paper illustrates the functional theory, developmental process and future tendency of related metasurfaces. We discuss the challenges and prospect on the future of imaging applications and systematic integrations with metasurfaces.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/5/2022-0234-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/5/2022-0234-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/5/2022-0234-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

Each amplifier design method is described and the current status of its research is listed in as much detail as possible. By comparing the four types of disk multi-pass amplifiers, it is found that the varying methods have distinct advantages and disadvantages. 4<italic>f</italic> relay imaging requires a vacuum environment to avoid gas ionization at the focal point, making the mechanics and adjustment more difficult; the resonant cavity design/optical Fourier transform concept multi-pass amplifier has a small spot at the mirrors, making it more suitable for lower energy multi-pass amplifiers; the near collimated beam transmission method has great development potential because it does not require a vacuum environment, but accurately controlling the surface shape of the thin-disk is difficult while the laser is operating. Therefore, from the perspective of laser design, it is necessary to continue to optimize the design of the thin-disk multi-pass amplifier to realize the diversification of application scenarios and the sustainable expansion of output energy.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/5/CO-2023-00092591103e-032d-4516-a28e-100cadbd3aa3.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/5/CO-2023-00092591103e-032d-4516-a28e-100cadbd3aa3_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/5/CO-2023-00092591103e-032d-4516-a28e-100cadbd3aa3.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

It can image the neural activity of freely moving vivo animals in real time, providing an unprecedented way to access neural signals and rapidly enhancing the understanding of how the brain works. Driven by the needs of brain science research, there have been many types of miniature head-mounted single-photon fluorescence microscopes, such as high-resolution imaging, wireless recording, 3D imaging, two-region imaging and two-color imaging. In order to have a more comprehensive understanding of this new optical neuroimaging technology, we classify its technologies according to the imaging field of view, introduce the characteristics of different types of micro-head-mounted single-photon fluorescence microscopes reported so far, and focus on the optical system scheme and optical performance parameters used. The advantages and disadvantages of different schemes are analyzed and compared and the future direction of development is described to provide reference for the practical application of brain science researchers.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/5/CO-2023-0007-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/5/CO-2023-0007-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/5/CO-2023-0007-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

In this paper, we review the reconstruction algorithm for NLoS imaging tasks. Firstly, considering the crossover and non-independent phenomena existing in the NLoS imaging classification, we use the different features of physical imaging models and algorithm models to reclassify them. Secondly, according to the proposed classification criteria, we respectively review the traditional and deep learning-based NLoS imaging reconstruction algorithms, summarize the state-of-the-art algorithms, and derive the implement principle. We also compare the results of deep learning-based and traditional NLoS imaging reconstruction algorithms for reconstruction tasks. Finally, the current challenges and the future development of NLoS imaging are summarized. Different types of NLoS imaging reconstruction algorithms are comprehensively analyzed in this review, which provides important support for the further development of NLoS imaging reconstruction algorithms.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/3/CO-2022-0186-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/3/CO-2022-0186-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/3/CO-2022-0186-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

The QTF has the advantages of low cost, small volume, high sensitivity and wide spectral response range, and the LITES is becoming a vital method for trace gas detection. In this paper, the basic principle of gas concentration measuring based on LITES is firstly analyzed. Secondly, from the perspective of various technical methods, this paper introduces the methods for improving the sensitivity of QTF detectors, and reviews the research progress of LITES system in recent years. The performance of these systems is evaluated by the signal amplitude, Signal-to-Noise Ratio (SNR), minimum detection limit, and Normalized Noise Equivalent Absorption (NNEA) coefficient. Finally, the practical application of LITES in the field of gas detection technology is briefly reviewed, and the methods for further improving its sensitivity are summarized and prospected.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/2/CO-2022-0137-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/2/CO-2022-0137-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/2/CO-2022-0137-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

Quickly and accurately understanding the temperature, humidity and pressure information of the atmosphere and their changing trends is of great significance to research on meteorology, climatology, and artificial weather research. Raman lidar can obtain various atmospheric environment-related parameters by separating Raman scattering signal inversion, which can achieve high accuracy detection of atmospheric parameter profile information. Raman lidar has unique advantages and potential in atmospheric temperature, humidity and pressure detection. With an introduction to the principle and inverse analysis algorithm of Raman lidar for atmospheric temperature, humidity and pressure detection, this paper also highlights the advantages and disadvantages along with related advances of spectral devices such as filters, etalons and gratings commonly used in Raman lidar. The detection techniques involved in Raman lidar are also included. Finally, typical applications of meteorological parameter measurements by Raman lidar are shown.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/2/2022-0145-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/2/2022-0145-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/2/2022-0145-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

In order to obtain more detailed information on the target, domestic and foreign researchers have carried out relevant research in different technical directions. In this paper, through the technical classification of remote sensing imaging, we introduce a representative aerospace optical remote sensing high-resolution imaging system. It focuses on monomer structure, block expandable imaging, optical interference synthesis aperture imaging, diffraction main mirror imaging, optical synthetic aperture and other technologies. It provides a new idea for the development of high-resolution optical remote sensing loads on the ground.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/2/CO-2022-0085-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/2/CO-2022-0085-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/2/CO-2022-0085-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

In recent years, a strong interaction between light and matter in periodic optical systems has been discovered, which is called Bound States in Continuum (BIC). Optics BICs are special electromagnetic eigenstates whose frequencies lie in the radiation continuum but are completely localized, and have shown interesting physics and rich application scenarios. This paper systematically reviews the classification and theory of BICs in periodic optical systems, and summarizes their basic physical properties and the latest application development. BICs in periodic optical systems are injecting new impetus into the fields of integrated optics, information optics, bio-optics, topological optics, and nonlinear optics.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/1/2022-0189-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/1/2022-0189-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/1/2022-0189-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

In this paper, we review the recent research progress in the material synthesis and optical characterization of Bi<sub>2</sub>O<sub>2</sub>Se. Firstly, the synthetic method and growth mechanism of 2D Bi<sub>2</sub>O<sub>2</sub>Se are introduced, including Chemical Vapor Deposition (CVD), wet chemical process, Molecular Beam Epitaxy (MBE) and Pulsed Laser Deposition (PLD), etc. Via steady-state spectrum study, the properties change of 2D Bi<sub>2</sub>O<sub>2</sub>Se with thickness change can be studied, such as the band gap. The defect type, temperature coefficient and thermal conductivity of 2D Bi<sub>2</sub>O<sub>2</sub>Se material can be further studied by focusing on the crystal vibration mode. Transient spectrum techniques can benefit the study of relaxation process and carriers transport properties in 2D Bi<sub>2</sub>O<sub>2</sub>Se materials. Finally, we summarize the existing challenges and application prospects for the promising Bi<sub>2</sub>O<sub>2</sub>Se field.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/1/CO-2022-0071-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/1/CO-2022-0071-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/1/CO-2022-0071-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

It has many advantages, such as shortening the operation time, reducing the risk of intraoperative bleeding, improving the prognosis and shortening the postoperative recovery time. It has important application value in minimally invasive surgery and preoperative examination. It is a research hotspot in recent years. This paper combs the panoramic endoscopic imaging technology from two aspects: principle and product applications. Firstly, various panoramic endoscopic imaging technologies based on two-dimensional and three-dimensional imaging are reviewed, their implementation methods are described, and their key indexes and performances are analyzed. Secondly, the capsule endoscope, panoramic enteroscope and other different types of products derived from panoramic endoscopic imaging technology are compared and analyzed, and the development trend and application prospect of panoramic endoscopic imaging technology are prospected.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/1/2022-0074-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/1/2022-0074-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/1/2022-0074-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

Its application value is high in the fields of frequency doubling, pumping, optical communication and sensing, which makes it a popular research topic in recent years. This paper firstly went over the mainstream structure and characteristics of monolithic integrated MOPA, including a tapered amplifier, ridge amplifier, Bragg grating and three-section MOPA. Based on their working principles and performance characteristics, we introduce the main research directions and the latest development trends in combination with their problems. Aiming at the problem of beam quality degradation at high power in monolithic integrated MOPA, the optimal design of epitaxial layer structure, facet optical film and electrode aspects are then summarized for monolithic integrated MOPAs. After that, we sort out the research progress of MOPAs with different performance characteristics for various application requirements including high power, narrow linewidth, high beam quality and high brightness. Finally, we prospect the development trend of monolithic integrated MOPA.</p></span> </div>  <div class="curtu device curtu-show"> <div class="picBox" > <ul class="picList clear"> <li class="item"> <a class="group3" title="" href="/fileZGGX/journal/article/zggx/2023/1/2022-0022-1.jpg"> <img srcl="/fileZGGX/journal/article/zggx/2023/1/2022-0022-1_mini.jpg" onerror="this.onerror=null;this.src='/fileZGGX/journal/article/zggx/2023/1/2022-0022-1.jpg'" class="figure_img" id="Fig-1" ref="#Fig-1" style="max-width:450px;

The recently-developed upconversion luminescence nanoparticles with orthogonal excitation-emission properties have attracted especially strong research interest because their distinct luminescence outputs can be dynamically modulated by switching the excitation conditions. The orthogonal luminescence properties further endow such nanocrystals with a set of new features and functionalities, which largely expands their potential applications. This review summarizes the progress in the development of orthogonal upconversion luminescence of rare earth ions, and provides a systematic discussion on design principles and construction strategies of orthogonal excitation-emission systems based on core-shell structures, as well as introduces their recent advances in various fields of applications including data storage, security anti-counterfeiting, digital displays, sensing, bioimaging and therapy. Furthermore, the prospective opportunities and challenges in the future research of orthogonal luminescence systems are also provided.</p></span> </div>  <div class="curtu device curtu-show"> <div
