分布式光纤振动传感器得到了广泛的研究，并在传感器全景中发挥着重要的作用。当外界振动作用在传感光纤上时，光的强度、相位、偏振态或光频率等光学参数都会发生变化。本文综述了分布式光纤振动传感的各种技术，从干涉传感技术(如Sagnac、Mach-Zehnder和Michelson)到基于后向散射的传感技术(如相敏光时域计、偏振光时域计、光频域反射计)，以及干涉术和后向散射法的一些组合。文中介绍了它们的工作原理，并介绍了它们的最新研究成果。最后对分布式光纤振动传感器的应用进行了总结，主要包括结构健康监测和周边安全等方面。总体而言，分布式光纤振动传感器具有监测规模大、隐蔽性好、灵活性好、抗电磁干扰能力强等优点，在各种实际应用中显示出相当大的潜力。
Distributed fiber-optic vibration sensors receive extensive investigation and play a significant role in the sensor panorama. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferometric sensing technology, such as Sagnac, Mach–Zehnder, and Michelson, to backscattering-based sensing technology, such as phase-sensitive optical time domain reflectometer, polarization-optical time domain reflectometer, optical frequency domain reflectometer, as well as some combinations of interferometric and backscattering-based techniques. Their operation principles are presented and recent research efforts are also included. Finally, the applications of distributed fiber-optic vibration sensors are summarized, which mainly include structural health monitoring and perimeter security, etc. Overall, distributed fiber-optic vibration sensors possess the advantages of large-scale monitoring, good concealment, excellent flexibility, and immunity to electromagnetic interference, and thus show considerable potential for a variety of practical applications.
