| 摘 要： | 为了分析大气湍流对高斯光束产生的光强起伏现象,采用相位屏的方法,模拟出高斯光束经过大气湍流后在接受面上的光场分布情况,然后对模拟出的光场进行分析得到光强起伏的方差,并与理论得到的静态统计量进行分析比较,在一定程度上得到了较好的吻合。这一结果对各种近地激光应用是有帮助的。

| Abstract: | In order to study irradiance scintillation after laser propagating though atmospheric turbulence,the method of phase screen was adopted to simulate the optical field in the receiving plane.The computed error of root mean square of the scintillation was compared with that in theory and they accord with each other to a certain extent.The above result is helpful for all near-earth laser application. |
