摘要

摘要: 快速转向反射镜（FSM）也叫扫描镜，是空间通信、自适应光学等领域的关键器材之一，用以在目标和接收器之间调整光束方向。随着实际应用需求的多样化，国内现有的快反镜已越来越不能满足高端领域的需求。针对国内仅有传统的单面工作扫描反射镜研究的现状，从反射镜工作场合需要双面扫描的特定需求着手，设计出双镜面工作的反射镜结构与镜面支撑方式，选用压电陶瓷作为驱动器，分析并设计出在多角度具有良好柔性的柔性支撑结构与具有放大机构的底座结构，进而给出一种基于压电效应，从而实现快速倾斜的双面反射镜装置，最后运用有限元方法仿真分析对所提出的设计方法与结构进行验证。

Abstract: Fast steering mirror (FSM) is also called Scanning Mirror. It is one of the key equipments in space communication, adaptive optics and other fields, which is used between the object and optical receiver to control the direction of light beams. Since the diversified demand of practical application, domestic fast steering mirrors are increasingly unable to meet the demand for high-end areas. According to the current domestic situation that only traditional one-sided scanning mirrors are studied, we design the mirror structure of double-sided scanning in the workplace which can realize working of both sides and the way to support the mirror so as to meet the specific requirement. Piezoelectric ceramics were used as the actuator. The support structure possessing fine flexibility in multiple directions and the base structure with amplification mechanism were analyzed and designed. Then a kind of device based on piezoelectric effect, consequently, making the double-sided mirror fast slope possible was given. Finally, the finite element method was applied to simulate and verify the design method and the entire structure presented in this paper.
