【摘要】 分析了影响转镜扫描相机时间分辨率的各种因素,给出了极限时间分辨率和基于相机动态摄影分辨率计算的时间分辨率的理论计算公式和结果。结合国内普遍使用的SJZ-15型转镜扫描相机,用自研设备动态像质检查仪和100ps超短脉冲激光照明两种测试方法,计算出了该相机钢转镜和铍转镜在不同转速下的实测时间分辨率值,并对数据进行了分析、比对和讨论。实测数据表明:钢转镜的转速为12×104 r/min,其最高时间分辨率约为8ns;铍转镜的实用最高转速为30×104 r/min,其最高时间分辨率约为4ns。更多还原

【Abstract】 The influence of time resolution was analyzed.The formulas of limited time resolution and based on dynamic photograph special resolution were given.The time resolution measured of steel mirror and beryllium mirror for model SJZ-15 rotating mirror steak camera was obtained with instrument of dynamic special resolution and 100 ps pulse laser.The data has been analyzed.The results show that the best time resolution is 8 ns and 4 ns approximately at 12×104r/min of steel mirror and 30×104r/min of beryllium mirror respectively.更多还原
