摘要

针对离轴反射光学系统的精密装调问题，提出了一种高精度空间交互测量以及基准传递系统，可实现调焦角度与系统光轴的高精度角度定位。该系统口径为450 mm，可实现0.5 km至无穷远的调焦，调焦角度精确定位后，只需调整无穷远处离轴三反光学系统的波像差满足要求，即可保证系统各个调焦位置处的波像差均满足设计要求，大大提高了装调效率。装调实验结果表明，无穷远处系统的波像差结果为0.09λ，1.5 km处系统的波像差为0.1λ，2.5 km处系统的波像差为0.11λ，0.5 km处系统的波像差为0.2λ，均优于设计要求。

Abstract

A space interactive measurement and datum transmission system with high accuracy was proposed

aiming at precise alignment problem of off-axis reflective optical system. Therefore the highly accurate angle location of focusing angle and systemic optical axis was realized. The diameter of the system was 450 mm

and focus-adjustable range was from 0.5 km to infinity. After accurate positioning of focusing angles

only wave aberration of off-axis three-mirror optical system in infinite position needed to be adjusted to satisfy requirements

and the wave aberrations of all focus position in the system could be guaranteed to accord with design requirements

thus improving adjustment efficiency greatly. The experimental results show that the wave aberrations of the system in infinite position

1.5 km

2.5 km and 0.5 km are 0.1λ

0.11λ

0.5km and 0.2λ respectively

which are all better than design requirements.
