摘　　要：对自行研制的能同时补偿一阶和二阶偏振模色散的自适应补偿器作了详细介绍。以光波偏振度(DOP)为监控信号,用局部邻居结构的粒子群优化算法(LPSO)为逻辑控制算法,使搜索时间低于100ms,跟踪过程响应时间为16ms,基本实现了实时跟踪补偿。A self-made adaptive compensator to compensating the first- and second-order PMD at same time is introduced, in which DOP is used as signal for monitoring. The algorithm, Local neighborhood structure of Particle Swarm Optimization (LPSO), is firstly used in optimum searching and tracking process. The searching process is finished within one hundred milliseconds and the response time of tracking process is 16 milliseconds. The quasi-real time adaptive PMD compensation is realized.
