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。
The primary rmrror an important componem of optical system applied on aspace 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-optlcal analysis based on integrated analysis technique. According to optical design requirement and the calculating results, the allowed temperament ranges of primary mirror are given.
