Research and Implementation of Communication System for Portable Digital Laser Communication Equipment

便携式数字激光大气通信设备是利用现代的太空科技转化为民用的一种尝试,是一种点对点的无线激光大气通信设备,也称自由空间激光通信。该设备中,信息是以激光束为载波,直接利用激光在大气或外太空中进行信号传递。整个系统传输信息量大,设备较轻,机动灵活,保密性好。且该设备在极端的环境下应用自如,不需要外部任何基站,可以满足日常的通信需求,也能实现通信功能。本文就这设备的通信系统部分的设计过程展开论述,阐述这模块的实现过程。

Portable digital laser atmospheric communication equipment is an attempt to convert modern space technology into civilian use.It is a point-to-point wireless laser atmospheric communication equipment,also known as free space laser communication.In this device,the information is transmitted by laser beam as carrier,directly using laser in the atmosphere or outer space.The whole system has the advantages of large amount of information transmission,light equipment,flexibility and good confidentiality.Moreover,the device can be used freely in extreme environments without any external base stations,which can meet the daily communication needs and achieve communication functions.In this paper,the design process of the communication system part of the equipment is discussed,and the realization process of this module is described.
