折转光管在光电瞄准系统中的应用

介绍了折转光管在瞄准系统中的使用位置、结构、工作原理和装调方法，分析了折转光管安装误差和两块平面反射镜之间的装调误差对方位传递精度的影响。使用MATLAB软件编程、计算、绘制出方位传递误差和高低传递误差的统计直方图，其分析结果为折转光管的装调提供了指导数据。计算分析表明，影响折转光管方位传递误差的主要因素是折转光管中两平面反射镜的装调误差，只要两平面反射镜的装调满足技术要求：方位误差≤4”、高低误差≤0．5’，即使折转光管在3个方向的安装误差极限值达到15°，也可满足折转光管方位传递误差≤10”的设计要求。

Application of reflex light-tube to photoelectric pointing system

The location, structure, working principle and the assembling method of a reflex light-tube in a photoel＇ectric pointing system are introduced, meanwhile the effects of installation error and assembling error of the reflex light-tube between two plane mirrors on the accuracy of azimuth transfer are analyzed. Matlab soft- ware is used to compute and draw the statistic histograms of the azimuth transfer error and the elevation error, and the results provide a guidance for the assembling reflex fight-tube. According to the results from calcula- tion and analysis, the main factor affecting azimuth transfer error of reflex light-tube is the assembling error be- tween the two plane mirrors in the reflex light-tube. As long as the assemble error between the two plane mir- rors satisfies the technical requirements of azimuth error ≤4＂ and elevation error ≤ 0. 5＇, the azimuth transfer error of the reflex light-tube can be ≤ 10＂ even the installation error extrema in three directions of the reflex light-tube reach 15°
