摘要

为满足野外检测多波段光电设备光轴平行性的检校需求，研制了一套便携式多光轴平行性检校系统。系统采用反射式卡塞格林光学系统和ZnS晶体靶板，为被校系统提供无穷远的十字分划目标并以此作为瞄准基准，完成对被校系统电视轴和红外轴之间的平行性检校；采用CCD系统完成分划板十字线和靶纸上激光光斑的采集，并利用数据处理系统检测出分划板十字中心与激光光斑中心位置的偏差量，完成对被校系统激光光轴与可见光轴之间的平行性检校。利用高精度光学角规对所研制的检校系统进行了标定，精度可达亚秒级。实验结果表明，该检校系统测量电视轴与红外轴之间平行性标准不确定度为2″，检校激光瞄准轴与发射轴平行性标准不确定度为5″。

Abstract

To satisfy the need of field measurement of the multi-optical axes parallelism of photoelectronic equipments, a portable axes parallelism calibration system is developed. The collimation of Cassegrain optical system and ZnS reticle is used in the system to create infinite reticle object and to provide aiming baseline for the original system and realising the parallelism calibration between television axis and infrared axis. A CCD system is adopted to collect crosswire on the reticle and laser facula on the target sheet. On the basis of the bias between the detected reticle centre and laser spot centre, parallelism calibration for laser axis and visible axis is achieved. An optical angle gauge is applied in this system to make calibration precision to approach angle second level. Experimental analytical results show that the standard uncertainty of this measurement for the parallelism between the TV-axis and the infrared-axis can reach 2″ and the standard uncertainty of this measurement for the parallelism between the sighting axis and the receiving axis of laser can reach 5″.
