摘要
针对高分辨率长焦距光学系统的结构特点,在受到轨道舱直径4 m左右结构限制的情况下,长焦距光学系统的结构长度的减小显得非常重要。通过像差理论计算和ZEMAX光学设计软件的设计,在满足了超长焦距高分辨率和结构长度小于4 m的要求的情况下,设计了一个视场为1.5°×0.3°、相对口径为1/9、焦距长度为23333 mm,结构长度做到了3314 mm的光学系统。系统采用了两个椭球面和一双曲面,还有两个平面折叠镜。其中平面折叠镜不仅可以缩短光路,还可以起到调焦作用。
According to high-resolution optical system with long focal length of the structure characteristics and structural constraints of the orbital module in diameter 4 m, the length of the optical system is considered one of the important factors for design. Therefore, a long focal length design of the structure above the optical system is particularly important. By the aberration theory and ZEMAX optical design software, the system to meet the ultra- long focal length and high-resolution requirements and the structure of the length is less than 4 meters. A system with a field of view 1.5°×0.3°, the relative diameter of 1/9, the focal length 23333 mm length of the optical system and the length of the structure was 3314 mm was designed. Two ellipsoid ,a pair of hyperboloid and two plane mirror to be the folding mirrors are used in the system. The folding mirror can not only shorten the optical path, but also play a role in focusing.
