摘　　要：成像探测器的装配定位状态对光电侦察系统的性能有重要影响,装调过程中探测器像面的倾斜、平移、旋转、位置等都会带来多维度误差,导致超视距观测系统成像探测器的像面失调,造成图像模糊、光轴偏移等现象。本文设计和搭建了一套光学测量系统,采用灰度梯度的图像清晰度评价方法,自动判别成像探测器的装调误差。光学测量系统对成像探测器的装调精度可达0.015 mm,并且可以根据系统成像的多感兴趣区(ROI)灰度梯度值的误差大小,给出装调的合格性判断。该光学精密装调系统为实现“以机代人”对探测器进行多维精确量化装调奠定了基础。The positioning state of the imaging detector assembly has an important influence on the performance of the photoelectric reconnaissance system.The tilt,translation,rotation and position of the detector image plane will bring multi-dimensional errors during the installation and adjustment process,leading to the image plane imbalance of the imaging detector in the over-the-horizon observation system,and resulting in image blur and optical axis offset.A set of optical measurement system was designed and built,which adopted the image sharpness evaluation method of gray gradient to automatically judge the installation and adjustment errors of imaging detector.The installation accuracy could reach 0.015 mm,and the qualification judgment of the installation could be given according to the errors of the gray gradient value of the multi-region of interest(ROI)image of the optical measurement system.The optical precision assembly system lays a foundation for the realization of multi-dimensional accurate quantitative assembly of the detector by"mechanical agent".
