摘要

摘要:由三块反射镜组成的光学系统在轨道空间微重力的影响下，其反射镜面间隔、曲率半径往往发生改变，对系统的后截距产生较大的影响，最终导致相机离焦，成像质量下降。通过分析三反系统的等效高斯光学系统，得到其后截距公式；通过齐次坐标变换，得到反射镜面刚体位移公式；通过采用最小二乘算法拟合计算得到微重力环境下的镜面半径，计算出相机在空间环境下的离焦量为0.04 mm，为调焦机构的设计提供了理论依据。

Abstract:The mirror interval and radius of curvature of optical system including three mirrors are often changed due to the impact of space microgravity, which has a greater impact on the back focal length, and causes camera defocus and imaging quality reduction. Through the equivalent Gauss optical system analysis of three-mirror system, back focal length formula can be obtained. By homogeneous coordinate transformation, the reflection mirror rigid-body displacement formula is obtained, and a mirror radius is obtained in the microgravity environment using the least squares fitting algorithm. Finally, by calculating the camera in space microgravity environment, the defocusing amount is 0.04 mm. Results provide a theoretical basis for the design of focusing mechanism.
