激光主动探测拼接光学系统的装调设计

Alignment design of assembly optical system for laser active detection

介绍由两组视场为8°×6°的光学系统在水平方向拼接为视场不小于15°×6°的探测接收系统。为保证其在整个探测视场范围内的视场拼接质量和角定位精度,对该探测接收系统的装调方法及流程进行了详细设计,对各装调步骤的精度指标进行了分配。重点针对折转光路的光轴平行性、分辨率以及视场拼接的装调方法及要点进行阐述。通过对各装调步骤的精度进行严格控制,最终探测接收系统的测试结果为:焦距f′=52.7 mm、视场15.2°×6.2°,达到设计指标要求。

The detection and receiving system with field of view(FOV)no less than 15°×6°was introduced,which was composed of two groups of optical systems with 8°×6°FOV in the horizontal direction.In order to ensure the splicing quality and angular positioning accuracy of the FOV within the whole of the detection and receiving system,the installation and adjustment methods as well as procedures of the detection and receiving system were designed in detail,and the accuracy indexes of each installation and adjustment step were allocated.Focusing on the optical axis parallelism,resolution,FOV splicing installation and its key points were described.Through strict control of the accuracy for each installation and adjustment step,the final test results of the detection and receiving system are as follows:the focus f′is 52.7 mm,the FOV is 15.2°×6.2°,which meet the requirements of the design indexes.
