这是对当前最先进的能够量化高频动态振动的分布式光纤传感器的回顾。研究了用于分布式动态测量的相位 OTDR 传感技术的最重要方面。分析了用于测量动态扰动的三相 OTDR 传感技术的原理，随后对该领域的最新进展进行了案例研究。
This is a review of the current state of the art distributed optical fibre sensors capable of quantifying high frequency dynamic vibrations. The most important aspect of phase-OTDR sensing technique which has been used for distributed dynamic measurement are studied. The principle of three phase-OTDR sensing techniques used to measure dynamic perturbations are analyzed followed by a case study of the most recent advances in this field.
