摘　　要：分析了高速转镜式条纹相机扫描速度不均匀性的起因,同时介绍了通过光电转换的手段测量扫描速度以及其不均匀性的方法,主要是利用激光的抗电磁干扰及可高速处理的性能得到转镜的时间信息。时间测量的精度达到了±125 ps,比以往的测试方法提高了1个数量级以上,速度测量精度达到扫描速度的0．1％。The causes of the non-uniformity of scanning speed for high speed rotating-mirror streak camera are described, and the measuring method of scanning speed and its non-uniformity by means of photo-electrical conversion is also introduced. This method acquires the time information of rotating mirror by the laser＇s capability of resisting the magnetic interference and being processed quickly. The uncertainty of measuring time achieved is 4-125 ps, making an order of magnitude improvement in accuracy. The speed measuring precision achieved is 0.1% of the scanhing speed.
