摘要
自由空间激光通信是一种新兴的通信方式,是光纤通信和无线通信结合的产物。其中,高精度、宽带宽的激光捕获,以及对准和跟踪(APT)是非常关键的技术。简述APT系统结构与其工作过程,并介绍了其中的关键技术,对捕获方法以及跟踪瞄准的精度做进一步分析,通过分析误差得出一个最优值。
The free-space laser communication is a new communication technology and a combination of optical fiber communication and wireless communication,in which the high-accuracy wide-band laser acquisition,alignment and tracking（APT） are the key techno-logies.The system architecture and its working process of APT are discussed,and the key techno-logies are introduced.The acquisition methods,tracking and pointing accuracy are further analysed,and an optimal value is given by the error analysis.
