设计了一个装调检测辅助系统,可完成外场条件下CO_2激光发射装置光轴平行度的快速检测。介绍了辅助系统的工作原理和检测装调过程,对影响检测精度的误差因素进行了分析和计算,着重分析了由辅助系统的装调和结构变形引起的误差,检测精度为5.3″。与大口径平行光管检测法进行了对比,结果表明,相对误差不大于1″。 A loading control system is designed to detect the parallelism of the optical axis of CO_2 laser emitting device under external field conditions. The working principle of auxiliary system and the process of assembly and disassembly are introduced. The error factors affecting the accuracy of detection are analyzed and calculated. The errors caused by the loading and adjustment of the auxiliary system are analyzed emphatically. The detection accuracy is 5.3 “ Parallel light pipe detection method was compared, the results show that the relative error of not more than 1 ”.
