根据航天遥感系统设计要求, 以及航天遥感光学的常用结构分析, 最终选用用离轴三镜反射镜光学系统结构。使用MATLAB软件编程计算光学系统的初始结构。并对光学系统全视场成量进行分析, 分别用MTF和点列图两种衡量标准对光学系统成像质量分析。

According to the design requirements and common structure analysis of aerospace remote sensing system, the off-axis three reflective optical system structure is chosen. MATLAB software is used to calculate the initial structure of the optical system. And the imaging quality in full field of view of the optical system is analyzed. Two measurement standards such as modulation transfer function (MTF) and spot diagram are used respectively to analyze the imaging quality of the optical system.
