摘要
目标高分辨光学成像在众多光电工程领域中具有重要的应用价值。然而,在很多目标观测场景中,光波都要经大气进行传输,从而导致成像质量的退化,克服复杂大气干扰获取高质量图像一直以来都备受各国学者的关注。特别是近年来随着激光技术的进步,由于激光雷达在距离分辨、三维成像等方面的优势,主动成像技术也取得了很大发展,其中大气的影响和校正同样是一项不容忽视的问题。大气对成像的影响主要包括两个方面:大气湍流和大气悬浮粒子。针对这两方面对成像的影响进行分析,同时对国内外学者发展的消除大气影响、进行高质量成像的主要技术进行了简要介绍,并结合本课题组在相关领域的长期研究,对几个值得关注的方面进行了总结和展望。
High-resolution optical imaging of target has important application value in many optoelectronic engineering fields.However,in many target observation scenarios,light waves are transmitted through the atmosphere,which leads to the degradation of imaging quality.Obtaining high-quality images by overcoming complex atmospheric interference has always attracted the attention of international scholars.Especially in recent years,with the advancement of laser technology,due to the advantages of lidar in distance resolution and three-dimensional imaging,active imaging technology has also made great progress,in which the influence and correction of the atmosphere is also a problem that cannot be ignored.The impact of the atmosphere on imaging mainly includes two aspects:atmospheric turbulence and atmospheric suspended particles.Firstly,the impact of these two aspects on imaging is analyzed,and then some main techniques for eliminating atmospheric influences to obtain high-quality images are briefly introduced.At last,combined with long-term studies of the research group in related fields,several aspects that deserve attention are summarized and prospected.
