摘要
文中介绍了激光通过大气随机信道的光强分布测试系统的结构、工作原理和关键技术,在设计激光光斑测量系统基础上,进行了不同气象条件下的视距实验测量,给出了不同天气情况下的测量结果并进行了分析和讨论。用此系统可以方便、准确、形象地观测激光通过大气随机信道后光强的变化情况,为进一步建立大气随机信道模型提供了有力的依据。
In the paper we introduce the structure, operational principle and critical skills of the testing system for the laser beam through atmosphere. We did the experimental measurement in line-of-sight laser link under different weather conditions, gave the experimental results under different weather conditions, at the same time analyzed and discussed it. With this system, it is easy to observe the optical power in atmosphere. It presents the strong reliance to further establish atmosphere random channel model.
