摘　　要：介绍了一种抑制太阳光干扰的光学系统,在给定了光学参数与结构参数下,采用传统光学系统很难抑制太阳辐射干扰。在经典卡式系统的基础上增加二次成像单元,并配合适当的遮光罩与挡光板成功解决了太阳光干扰的问题。卡式系统有效解决了空间狭窄中光学系统尺寸受限的问题,这样拦光结构在狭窄的空间内得以实施;二次成像系统使光学系统成功实现冷光阑匹配,较经典卡式系统大大提高了系统灵敏度同时有效地抑制了太阳辐射干扰。An optical system used to restrain sun light is introduced. The classical optical system is hard to suppress sun stray light at given optic and structure parameter. A reimaged part is added on cassegrain system, and several baffles are set to restrain sun light. Cassegrain system resolves the problem of limited size of optic system in small space, and the baffles can be installed in the small space. 100% cold stop efficiency is achieved by reimaging system. The ability of restraining sun light and sensitivity are improved compared to tradition Cassegrain system.
