摘要
针对激光在洋面上大气湍流中传输时,光能量分布发生变化,影响激光通信质量。本文基于大气光通信信道模型,对激光在大气湍流中的传输进行模拟,分析大气折射率结构常数、传输激光的波长,传输距离对光能量分布的影响,并用MATLAB对其影响进行了数值模拟。结果表明:在仅考虑大气湍流对激光传输影响的条件下,传输激光的波长对光能量分布具有重要影响。
In view of the laser energy distribution changes when it transmits in the atmospheric turbulence on the surface of the sea, which affects the laser communication quality. This article simulates transmission of laser in atmospheric turbulence by the atmospheric laser communication channel model,analyses the atmospheric refractive index structure coefficient and the wave length of laser and the transmitting range affect the laser energy distributed, make numerical simulation of influence with MATLAB. The result indicated：Only considers the condition that atmospheric turbulence influences on the laser transmission,the wave length of laser have the material effect to the laser energy distribution.
