摘要
为解决因建筑物晃动、风力影响等环境因素对大气激光通信通信的影响而提出自动跟瞄技术。主要探讨了该问题的一种解决方案:采用GPS定位技术和扫描技术进行粗瞄准,用四象限红外探测器(QD)进行精瞄准和实时跟踪。
The shaking of buildings, wind and other natural forces affect the free space optical communication, so we require the Acquisition Tracking and Pointing （ALP） Technology. Here we discuss about one solution to this problem, which is to use of GPS positioning technology and scanning technology for laser beam＇ s acquisition, and using QD for laser beam＇s pointing and tracking.
