对目前常用的多光谱多传感器融合光电系统光轴一致性的几种检测方法进行了分析、研究和比较,提出了一种实用新方法.该方法主要利用上转换板将红外波段的激光转换为CCD可探测到的可见光波段的红光并对光斑进行延时,使普通CCD能够很容易地探测到单、低频窄脉冲激光的光斑,在经进一步处理后,即可检测到发射出的激光光斑的形心、质心、尺寸等参数,以及激光光轴与光学观瞄装置光轴的平行性.

Several methods to detect the optical axes parallelism of multi-sensor electro-optical system were analyzed. The advantages and weakness of each method were compared. A practical method is proposed, which converts laser in infrared band to visible light detectable by CCD with an up-conversion plate. A red spot was generated on the plate and retained for a while. The spot generated by the low frequency single pulse laser can be detected easily by a CCD. After some further processing, some parameters of the laser such as centroid and dimension can be measured and the parallelism between laser path and optical observation path can be detected.
