| 摘 要： | 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″。 |
| 关 键 词： | 光学测量 光轴平行 快速检测 辅助系统设计 精度 |

| Abstract: | A novel assistant system is designed to test the optical-axis parallelism of the CO_2 laser launching equipment. The principle of the assistant system and its working process are introduced.The error factors which influence measuring accu- racy of the system are analyzed,the alignment of assistant system and its deformation are discussed.The evaluations shows that the testing precision reaches 5.3″,which can satisfy the actual requirement.By comparing with large-aperture collimator,ex- perimental results show that the difference of measuring value is less than 1″. |
| Keywords: | optical measurement optical-axis parallelism fast test assistant system design accuracy |
