摘要
文章从空间探测所广泛采用的三反光学系统入手,建立了一个研究光学系统玻璃自身辐射特性的模型,通过它计算得到低温光学系统的背景辐射量与温度之间的关系,并结合计算结果分析了典型红外空间望远镜的探测能力。
The paper starts with three-mirror optical system that is adopted widely in space exploration, then establishs a model that researches the radiation characteristic of mirror of optical system. The relation between background radiation quantity and temperature of cryogenic optics system is calculated through the model. Further more the exploration ability of typical infrared space telescope is analyzed with the result.
