摘要: 针对光电跟踪系统稳定精度测试需求，提出一种稳定精度动态测试方法。该方法基于光学自准直原理，采用面阵CCD探测器，结合图像求取质心算法，实现被测系统的动态测试，通过该装置获得了稳定精度测试结果。结果表明：测试50 rad级两轴两框架系统动态稳定精度，通过该测试方法测出其稳定精度最大为48 rad。

Abstract: For the stability test requirements of precision optical tracking system ，we presented a dynamic testing method of stability accuracy. According to the optical auto-collimation principle，we utilized the CCD array detector combined with the computation for center of image to realize the dynamic test , and we required the test results of stability accuracy by this device. Experiments results show that for the 50 rad level two-axis two-frame system,the tested stability accuracy is up to 48 rad by our method.
