热光学分析 光学系统 主镜 温度梯度 成像质量 thermal-optical analysis optical system primary mirror temperature distribution image quality
摘要
主镜是空间望远镜光学系统的重要组成元件，其热光学特性将为光学系统的热控设计提供依据。利用建立在集成分析基础上的热光学分析方法，分析了某空间望远镜主镜在三种不同的温度分布形式，即在径向温度、轴向温度、周向温度梯度的作用下对光学系统成像质量的影响，结合设计的要求，根据计算结果给出了许用温度梯度的范围。
Abstract
The primary mirror is an important component of optical system applied on a space telescope,and its thermal optics property is the guideline to thermal design and control. Several kinds of temperature distribution such as radial,axis,cycle temperature distribution acted on the primary mirror of a space telescope on the effects of the image quality were analyzed used thermal-optical analysis based on integrated analysis tcchnique. According to optical design requirement and the calculating re-sults,the allowed temperament ranges of primary mirror are given.
