摘要
文章介绍了为分析大气随机信道对激光传输影响而进行的激光远场实验,即光斑测量实验和光强测量实验。根据实验的目的和原理,自行研制了两套实验系统:一套为光斑实时测量和记录系统,另一套为光强实时测量和记录系统。运用以上两套实验系统进行了激光远场实验,记录了大量实验数据。通过对实验数据的处理,绘制了不同天气条件下光斑重心的变化曲线和光强的变化曲线。从实验上论证了大气随机信道对激光远场光斑的影响,并得出了大气对激光传输影响的统计规律。
This paper introduces two types of real time systems developed for measuring laser beam and laser power,and for analysing the influence of atmosphere stochastic channel on laser transmission. One system is used for the real-time measurement and record of the laser facula,and another for the real-time measurement and record of the optical intensity. Lots of outfield experiments have been done and the experimental data have been recorded with the two systems. From the processing of the experimental data,some influence rules of atmosphere have been deduced.
