ASTRODⅠ的光学设计

THE OPTICS DESIGN OF ASTROD Ⅰ

本文讨论ASTROD Ⅰ的光学系统,包括对背景光影响的讨论、选用器件的依据和重要器件的介绍。本光学设计主要指航天器上望远镜后端的光学平台所包括的光学系统,这个光学系统能实现三个功能:1)连续激光束发射和接收的光路;2)脉冲激光束发射和接收的光路;3)航天器指向跟踪探测的光路。

This paper discusses the optics design of ASTROD Ⅰ. It also contains the discussion of. background light, the reason of optical elements selection and important elements illustration. The optics here is the optical system on the optical bench (OB). The OB is at the back end of the telescope in the spacecraft. The optical system fulfils three tasks: 1. to send out and receive CW laser light, 2. to send out and receive pulsed laser light, 3. spacecraft direction track and point.
