多光谱多光轴平行性检测方案设计与误差分析

模块化设计、多通道集成已成为当前光电装备研制的主流思路，但多个探测单元的光轴一致性却直接影响着光电装备的使用效能。现有方法难以兼顾多光谱、多光轴、高精度、大轴系跨度等多种光轴平行性检测需求，为此，本文提出了一种基于“反射式结构 +光轴平移”思想的多光谱多光轴平行性检测方案。采用“反射式结构”设计反射式平行光管，解决了多光谱范围内可见光、微光、激光、红外等不同波段光轴的平行性检测问题；利用“光轴平移”思想解决了大跨度范围内光轴间平行性检测问题。结果表明：本设计方案的平行性检测误差小于 0.134 mrad，可检测的轴系跨度可达 0.5 m，能够满足绝大多数光电装备的光轴平行性检测需求。

Abstract

The modular design and multi-channel integration has become the main thought of developing the pho-toelectric equipment, and the multi-axis parallelism directly influences the equipment performance. The current me-thods cannot meet the actual testing needs of multi-spectral, multi-axis, high-precise and large axis space. Thus a multi-spectral and multi-axis parallelism testing scheme is put forward by adopting the designing thought of reflective type and optical axis translation. The reflective collimator is designed to solve the multi-spectral and multi-axis par-allelism testing problems, and the optical axis translation design can increase the axis space of multi-axis parallelism test. The results show that the parallelism testing error is less than 0.134 mrad and the axis space can reach 0.5 m, which can satisfy parallelism testing needs of most photoelectric equipment.
