回顾了光束扫描技术的发展历程, 重点分析微机电式和纯电控非机械式光束扫描技术的特点, 并综合对比它们各自的技术优势, 最后指出在高速率光通信系统中, 由于纯电控非机械式光束扫描技术得到广泛应用, 因此必须考虑该技术的色散特性对高速光通信系统误码率的影响。

The development process of beam scanning technology is reviewed. The characteristics of beam scanning technology of micro-electromechanical system (MEMS) and mechanics-free electrical control modes are analyzed. And the technology advantages of those two technologies are compared synthetically. In high-speed optical communication system, the influence of chromatic dispersion characteristics of the technology on bit error rate of high-speed optical communication system must be considered due to the widely application of beam scanning technology of mechanics-free electrical control mode.
