摘要

光束受大气的影响很大。折射率的时空变化分布以及不同的天气条件都会导致光束的波动和衰减。为了改善信号接收,开发了空间分集、自动跟踪、自适应光学等多种减缓技术。本文主要讨论了在FSO网络中利用路由分集来提高链路可用性的三种链路分集测量方法。

Measurement statistics of three joint wireless optical links
Optical beams are highly affected by an atmosphere. Time and spatially variable distribution of the refractive index as well as different weather conditions result in fluctuation and attenuation of the optical beam. In order to improve signal reception, several mitigation techniques were developed for instance spatial diversity, auto-tracking, adaptive optics etc. This paper discusses utilization of route diversity in FSO networks primarily to increase the availability of the link based on three links diversity measurements.
