摘要

空间光学的发展对光学系统的轻量化提出越来越高的要求

作为一种超轻量化的方法

介绍了主动调节刚性支撑薄膜型反射镜的概念

这种薄模型反射镜由美国率先提出

并制造出口径500mm厚2mm的模型镜

反射镜的面形通过均匀分布的致动器的微量移动来调整

致动器的最小位移是20nm.美国使用压电陶瓷做致动器

有利于实现系统的轻量化.在试验阶段

设计一套机械微动装置来代替压电陶瓷做致动器

它的微动原理是利用杠杆减速机构及球面上的不同点的矢高变化来得到所需要的微位移

这套机构具有结构简易

重量轻

易于加工制造的特点

同时具有较高的灵敏度.

Abstract

Along with the development of space optics

the lightweighting of an optical system becomes more and more important. Membrane with active rigid support(MARTS) was first made at the University of Arizona. The mirror features lightweight and fine surface accuracy

and its surface can be adjusted by many actuators. The thickness of the membrane mirror is 2.1mm

diameter

530mm

and mass

1.25kg. The actuator designed on the principle of piezoelectricity has the micro-moving of 20nm. During the trial manufacture

the author made an actuator by the method of mechanism. Its principle of micro-moving is based on leverage and changing of height of arc in the spherical surface. It can realize 20nm micro-moving

too. This device is characterized by simple structure

high sensitivity and easy manufacturing.
