分布式光纤传感系统利用光纤既能传感又能传输信号的特性实现对光纤沿线振动、应变、温度等物理量的长距离连续测量，在周界安防、电网管道监控、大型结构健康监测等领域具有十分广阔的应用前景。上述的实际应用中，事件或故障的发生通常表现为振动、应变以及温度等物理量的改变，振动的探测频响高低、应变探测的动态响应能力以及多参数的同时测量都会影响事件的定位或预警。因此，振动的宽频测量、应变的动态测量以及多参数测量，对事件定位和信息完整捕获起着至关重要的作用，能够推动分布式光纤传感的应用发展。本文介绍了近年来在分布式光纤传感系统中，基于瑞利散射的宽频振动测量、基于布里渊散射的应变动态测量以及基于多散射的多参数测量取得的研究进展。
