中文摘要：

采用功率谱反演法与叠加低频谐波方式数值模拟静态湍流相位屏,并根据湍流冻结理论仿真了动态湍流相位屏。采用液晶空间光调制器（LC-SLM）在实验室内搭建了大气湍流信道仿真平台,进行了Kolmogorov湍流模型下,不同湍流强度的激光大气传输模拟研究,对比分析了实验结果,与理论较为符合。同时实验研究了不同模拟湍流强度下激光通信误码率的响应关系,这对实验室内评估实际激光通信系统的性能具有重要应用价值。

英文摘要：

Numerical simulations for static turbulent phase screens are presented with power spectrum method （FFT）. Also simulation methods for dynamic phase screen were presented by using traditional turbulence frozen method. An indoor atmospheric turbulence simulator was designed based on LC-SLM, and a simulation test bed was built. In the Kolmogorov turbulence laser propagation characteristic in different turbulent atmosphere was simulated. The experiments results were analyzed and showed the agreement with the theory. The response of bit error to intensity of turbulence were investigated, it is meaningful for value the laser communication system indoor test.
