摘要
大气激光通信曾被评为2001年十大热门电信技术之一。主要介绍了大气激光通信系统的组成及技术优点,提出了一种收发一体、光电分离的系统结构。总结分析了大气干扰、天气因素和平台的抖动或振动对通信的影响,提出了螺旋式扫描子空间的动态捕获、瞄准、跟踪方案。展望了大气激光通信广阔的应用前景。
Free space laser communication is recognized as one of the top 10 pop telecom technologies in 2001. This paper mainly introduces the composition of free space laser communication system and its technical advantages, presents a new integrative transceiver, optical antenna separated from the electronic components structure. The paper also summarizes and analyses how the atmosphere, weather and platform's sway or vibration affect the communication, presents a dynamic acquisition, pointing and tracking scheme including using helix-style subspace scan to catch the target. FSO has a wide prospect of application.
