摘要
为了研究大气湍流对激光传输的影响,以大气湍流的激光传输效应为基础,建立了激光到达接收面的光强分布模型。模型考虑了折射率结构常数、传输距离、发射面和接收面孔径以及湍流引起的光束展宽等参数,分析这些参数对接收面光强分布的影响,以此研究大气湍流对激光传输的影响,并提出降低湍流影响采取的措施。
In order to study the effect on laser propagation in the atmospheric turbulence, the model of intensity distribution on the receiver plane was derived based on laser propagation in the atmospheric turbulence. And the parameters like structural constant of atmosphere refraction coefficient, propagation distance, aperture of transmitter and receiver plane, and extended area caused by atmospheric turbulence were analyzed which impact on laser intensity distribution. This research focused on the effect on laser propagation in the atmospheric turbulence and proposes some methods to restrain the influence of turbulence.
