空间可展开主镜技术途径研究

Technical Ways for the Space Deployable Primary Mirror

可展开光学系统是实现特大口径光学遥感器的技术途径之一。可展开光学系统的主要特点是主镜分块、收拢发射、入轨展开,并且主镜超轻量化。文章主要介绍了实现可展开光学系统主镜的两种方法(超轻分块镜和超轻超薄分块镜),并对两者的实现难易程度进行了比较。

The deployable optics was an effective way to realize the large aperture optics. The main characteristic of the deployable optic was the primary mirror. The primary mirror was segmented, folded when launch and deployed in orbit. This paper gave two ways to realize the segmented primary mirror, one was the ultra-light semi - rigid mirror and the other was the ultra-light and ultra- thin active mirror.
