激光对准快速反射镜控制系统的设计
Design of a control system of fast reflector in a laser autocollimator
摘要
Abstract
In order to revise the light-route deviation of a laser autocollimator , a fast reflector control system of fast reflector in laser autocollimator control was designed .By adopting a step motor as power element , the movement of fast reflector in 2-D way was controlled, the light-route deviation of laser was eliminated and the light route of laser could be controlled accurately.The hardware and software of the fast reflector control system were expatiated exactly .Using hardware such as the laser autocollimator control box , the hardware and software design of laser autocollimator control system were validated.The experimental results show that root-mean-square of both azimuth errors and elevation direction errors are less than 1″when the working range of the fast reflector system is small , that is to say, the precision of fast reflector control system is less than 1″.Fast reflector control system can control the movement of fast reflector in 2-D way exactly.The hardware and software of the design is correct and reliable .The fast reflector control system can satisfy the demand of the laser autocollimator control system .关键词
