摘　　要：介绍一种用于检测多光路光电设备光轴平行性的测试系统,该系统采用准直平行光管提供无穷远目标,并融合了CCD图像采集处理和计算机技术,通过计算目标靶十字中心和激光光斑中心之间在CCD上的像素跨距,计算出红外、可见光以及激光三轴相互间的平行性误差,系统的计算误差小于5″。A system for detecting the parallelism of multi-channel optical axes was introduced,and a collimator was used in the system to provide an infinite target.Based on CCD image acquisition and processing and computer technique,the parallelism errors among the infrared axis,visible axis and the laser axis were calculated by calculating the pixels span in the CCD between the target cross center and the laser spot center.Result shows that the calculation error of the system is less than 5 ″.
