激光在雨中传输的分析与计算

Analyze and Calculate for Laser Transmit Through Rain

本文通过分析雨滴其对激光的散射和吸收作用,研究激光在大气中传输时受雨滴作用的影响,计算不同雨滴对激光光强的影响,在不同降雨下,测试激光光强的变化,并通过软件仿真实时显示光斑的闪烁、漂移,为进一步优化激光通信系统性能设计、最终实现全天候超视距的大气激光通信做有意义的探索。

The effect of scattering and absorption on laser is very important in rain drops. It was researched the effect of rain particle to optical communication through the analysis of atmo- spheric rain particle, and display the optical plot in time. The result of the investigation is im- portant to optimize capability of optical communication in day and night.
