摘要
窄光束的精确瞄准与跟踪是实现激光无纤通信,发挥其诱人特点的一个关键问题。本文针对激光大气通信给出了一个更简捷的自动瞄准方案。此方案无须要求通信系统具有能实现宽窄波束变换的光学系统,也不用预先解决收发天线共用的问题。整个方案的构思和系统结构图,以及系统主要参数的估算方法均在文内给出。
Automatic accurate pointing and tracking of narrow optical beam is a very im-portant problem for laser communication without fiber-optic.A new and direct automaticpointing plan suitable for atomosphere laser communication of fixed station is represented.Adopting this plan,it needs not to change beamwidth and there needs no common optical sys-tem for receiving and transmitting.The conception and the schematic diagram of the plan andthe estimation method for main parameter of system are given.All of this,as above,are alsouesfull for movable station.
