摘　　要：介绍了一种基于激光波形分析的脉宽测量方法,搭建了由高速光电探测器和高实时采样速度数字示波器组成的脉宽测量系统。实现了对二代和三代激光测距机调Q窄脉宽的快速测量,测量结果与实际相符。并得出探测器响应特性的非线性区域会引起脉冲失真;探测器上升时间决定了脉宽总上升时间,并且探测器上升时间越大激光脉宽的展宽越明显。This paper introduces a testing system comprising a hight responding detector and hingt sampling rate digital oscilloscope to mesure pluse width of laser range finder based on the wave analysis. This system can measure the Q- switched nerrow pluse width of the second and third generation laser range finder lastly, the results accord with the reality. The results show that the nonliner response characteristics of detector can cause the distortion, the rise-time of detector decides the pluse width＇s rise-time and the bigger the rise-time is,the widther the pluse width is.
