摘要
随着高分辨率观测技术的发展和高数据率信息传输的迫切需求,研究高速率激光通信的全光网络迫在眉睫。文章介绍了空间激光通信技术的优点及发展趋势,提出了可用于激光通信组网的几种光端机光学原理及系统方案,分析了多反射镜拼接形式光端机的APT控制模型,为空间激光通信链路组网提供了新的技术途径。
With the development of high resolution observation and urgent demand for high bit rate data transmission, studying high bit rate laser communication and all-optical networking is an urgent issue. In this paper, the basic requirement of space laser communication link and networking were analyzed. With special em- phasis being given to the technical difficulties and the new networking optical principles, firstly a new technical initiative has been put forward. Then ,APT controller model with multi-reflector of the optical-terminal-equip- ment was analyzed ,which provide a new technical way for the space laser communication link and networking.
