摘要
为实现对水平式两轴转台中库德光路的快速高精度装调,建立了自准直平行光管与平面反射镜相组合的自准直装调和检测系统。介绍了水平式两轴转台中库德光路的组成和工作原理,根据光学自准直原理给出了库德光路的装调和检测方法;结合库德光路的特点推导出基于坐标变换的库德镜辅助装调模型,进而实现了库德光路的快速装调。最后,对装调好的库德光路进行了随经轴和纬轴转动的误差检测,得出两轴转台工作过程中库德光路的实际晃动误差。结果表明,通过装调的库德光路晃动误差仅为5.2″,满足设计指标要求的8″。该装调技术不仅适用于库德光路也可对其它的反射镜装调提供一定的借鉴和参考。
In order to realize the fast and high accuracy alignment of Coude optical system in an alt-alt two axis tracking turntable, an auto-collimation alignment and testing system was built, which was composed of an auto-collimator with a flat reflector. The working principle and components of Coude optical system in the turntable were introduced, and its alignment and testing methods were proposed according to the principle of optical autocollimating. On the basis of the characteristics of Coude system, the principle of rectangular coordinate transformation was deduced and the fast alignment of Coude optical system was achieved with computer-aided alignment. The errors in Coude optical system with latitude and longitude axes rotated were measured. The results show that the wobble errors of Coude optical system aligned by this methods is 5.2＂, which is superior to the system precision expected by laser launching system in 8″, and meets the requirements of technology index. This methods can be widely used in the alignment of Coude optical system with the two axes rotated , and has broad application prospects in practical engineering.
