摘要

设计了基于高精度直线驱动器和曲柄滑块机构的高精度二维角度调节机构

以实现2 m口径望远镜中哈特曼探测器与自适应光学系统间的高精度对准与自动化调节。依据光学设计分析得出调节机构分别需满足±1°的调节范围和6"的调节精度。根据哈特曼探测器的外形结构和调节机构的整体布局

选择了调节机构中的主要参数

对整体调节机构进行了初始设计并分析了它的精度和动态特性。利用自准直仪设计了调节机构的检测系统

对设计的调节机构的调节范围、精度和动态性能进行了实际测量。结果表明:哈特曼探测器调节机构在俯仰和扭摆方向上的角度调节量均约为±1.2°

调节精度分别为0.43"和2.1"

均满足设计要求

为哈特曼探测器的高精度探测奠定了基础。

Abstract

A high precision two dimension angle adjustable mechanism based on a fine actuator and a slider-crank mechanism was designed to implement the fine alignment and automatic adjustment between Hartmann sensor and adaptive optical system in a 2 m diameter telescope. On the basis of the optical analysis

it points out that the mechanism needs ±1 ° adjustable amount and 6 "adjustable accuracy. Associating the use pattern of the actuator with the outline of the Hartmann sensor

main parameters of the adjustment mechanism were selected

the initial mechanism was designed and its accuracy and dynamic specialty were analyzed. Then

a detecting system for the mechanism was designed based on an autocollimator. The adjustable range and accuracy as well as the dynamic specialty were tested by the detecting system in the experiment. The results show that the adjustable angles on the pitch and azimuth directions are all about ±1.2° and the rotation angle accuracies in the pitch and azimuth directions are 0.43" and 2.1"

respectively

which all satisfy the design requirements. The research results provide a foundation for high precision detection of Hartmann sensors.
