摘要

高分辨力空间相机的光学系统决定相机的外形尺寸和布局，为了相机的小型、轻量化和结构稳定，对某一种光学设计指标要求，分析比较多种光学系统结构是有必要的。本文针对在太阳同步轨道上用TDI CCD 推扫方式成像的高分辨力可见光相机，设轨道高度为500公里，地面像元分辨力达到 0.5米，用 CODE V 软件分析研究了六种可能的相机光学系统结构，得到不同相对孔径和不同视场角的光学设计结果，并给出了可供参考的六种光学系统设计结果数据。在实际工程应用时应根据不同的地面覆盖宽度的需求确定光学系统视场角，然后根据不同的视场角选定能满足这个视场角要求并尺寸最小的光学系统结构形式。

Abstract

The dimension and configuration of space camera is mainly dependent by the optical system of the camera. It is useful for the space camera get small

light weight and stabilization that to study several optical system configurations for one application purpose. This paper describes high resolving visible space camera which takes sun synchronization orbit and TDI CCD push-bloom imaging method. Assume the orbit height is 500 km

the grand sample distance is 0.5 m. Analyzed six kinds optical system configurations using the CODE V optical design software

the obtained results have different F number and FOVs(field of view) of each others

and presents useful optical design data. In the practical applications

according to the ground swath width determine the FOV

then choice the optical system configuration which can satisfy the needed FOV and small dimension.
