【摘要】 本文提出了一种基于同心物镜结构的空间目标监视望远镜。首先介绍了国内外关于空间目标监视载荷的研制现状;然后进一步介绍了同心物镜系统的特点。并以美国杜克大学研制的AWARE-2相机和加州大学圣地亚哥分校研制的超广角相机为例,介绍了同心物镜系统实现平像场的手段:阵列转像物镜方案和光纤束拼接视场拼接方案。文中对比了两种方案的优缺点,对比结果说明了光纤束拼接视场拼接方案更适合应用于空间目标监视任务。最后,文中给出了两个不同指标要求的基于同心物镜结构的超大视场高分辨率望远镜的光学设计实例,有效视场分别是120°×30°和100°×50°,全视场内80%点斑能量半径都在5.3?m以内,全视场内在100lp/mm处传函都优于0.35。这两个实例的设计结果能满足大视场、长弧度、高分辨率的空间监视任务要求,可为今后空间目标监视望远镜的研制提供参考。更多还原

【Abstract】 Space surveillance telescopes based on monocentric lens are proposed.The development of space surveillance telescope at home and abroad is presented,and the characteristic of the monocentric lens are introduced.With the AWARE-2 camera developed at the Duke University and the wide field of view camera developed at the University of California,San Diego,for example,the method of realizing the flat image are introduced,which are the relay objective array and the fiber bundle image relay.The two methods are compared,and the results show that the fiber bundle image relay method is appropriate for the space target surveillance missions.Two optical design examples of space surveillance telescope with large field of view and high resolution based on monocentric lens are given,the field of view of which are 120°×30° and 100°×50°,respectively.In the whole field of view,the encircled energy radiuses(80%) are less than 5.3?m and the MTFs at 100lp/mm are larger than 0.35.The results of the two examples can meet the requirements of the space target surveillance missions with large field of view,long arc and high resolution.This paper can provide references for the development of space surveillance telescopes.更多还原
