二维跟踪指向镜结构设计与分析

Research on Structure Design of Two-dimensional Tracking Pointing Mirror

根据二维跟踪指向镜的系统组成,从摆镜设计、U形架设计和轴系设计三个方面阐述了空间激光通信光学系统前端的二维指向镜的机械结构设计。通过对转矩及轴系精度的分析,验证了设计的合理性,作为二维跟踪指向镜的模样设计,达到了预期的设计目标。

According to the two-dimensional tracking pointing mirror＇ s composition, the mechanical structure design of two-dimensional pointing mirror of optical system in the space laser communication system were elaborated from the pendulum mirror design, U-shaped frame design and shafting design three aspects. Through the analyzing of the torque and shaft accuracy, this design is verified reasonable. As a prototype of two-dimensional tracking pointing mirror, the expectant goal are achieved.
