摘要: 为实现对不同功率、不同远场距离激光束光斑分布的测量，本文分析了影响远场光斑测量的关键因素，给出了阵列式光电探测效应靶标的理论设计依据，研制的效应靶标可以满足5~100 kW激光系统在10~100 km距离范围内的远场光斑测量需求。解决了不同功率高能激光束在不同距离处远场光斑动态测量的技术难题，为激光光斑远场动态分布测量提供了一种有效的手段。

Abstract: To evaluate the distribution of laser beam spot with different powers under different far-filed distance, the key factors affecting the measurement were analyzed. A technical design basis for photoelectric detection effect target array was provided. The target developed in this research could satisfy the requirements of far-filed spot measurement of lasers whose power ranging from 5 kW to 100 kW within a distance range of 10 km to 100 km. This research solved the technical problems of dynamic far-filed spot measurement for high power lasers under different distance.
