摘　　要：激光远场光斑分布测量是研究高功率激光大气传输效应的有效方法,同时也是评估强激光武器作战效能的重要手段。设计了一种基于摄像和阵列探测相结合的复合测量方法,实现了强激光远场光斑时空分布的定量测量。该系统可用于波长为(1064±10)nm、功率密度动态范围为2~5000 W/cm2激光的远场光斑分布测量。The measurement of laser far-field facula distribution is an effective way to study the effect of high power laser transmission in atmosphere,and it is also an important means to evaluate the operational capability of high power laser system in a long distance.A new method based on the combination of imaging and array detection is proposed in this paper to measure the far-field spot spatial and temporal distribution of the high power laser.The system can be used to measure the far-field spot distribution of the laser with wavelength of（1064±10） nm and power density dynamic range of 2~5000 W/cm^2.
