摘要
为了满足空间遥感不同应用的需求，完成了4种型式的长焦距同轴三反光学系统设计。根据同轴三反光学系统设计理论，介绍了同轴三反光学系统设计初始结构设计方法，以工作谱段0．45-0．9μm、F数10、焦距10m为例，对4种型式的长焦距同轴三反光学系统进行优化设计，设计视场内获得接近衍射极限的成像品质，并分析和比较了这几种光学系统构型、元件布局、视场形式和焦面拼接方式的特点。空间观测领域的应用决定了长焦距同轴三反光学系统的型式。
In order to meet the need of various application, four kinds of coaxis three-mirror-anastigmat ,tem were designed. The design method of initial configuration of on-axis three-mirror-anastigmat system was outlined based on principle of on-axis three-mirror-anastigmat system, and four kinds of coaxis three-mirror- anastigmat system were optimized with spectral region of 0.45-0.9μm, effective focal length of 10m, f number of 10. These systems could achieve fine imaging quality that approached the diffraction limit over field of view. The characteristics of parameter of optical system, layout of components, field format and butting FPA were analyzed in this paper, It will be the application to space-based observations that determines the optical system configuration of coaxis three-mirror-anastigmat with long focal length.
