Pulse Coding in Distributed Optical Fiber Vibration Sensor: A Review
IEEE Sensors Journal（2021）
Abstract
Distributed optical fiber vibration sensor (DOFVS) is suitable for remote monitoring of vibration signals generated by external perturbations. In order to improve the sensing performance, various pulse coding techniques are applied in DOFVS, which have attracted an increasing amount of research attention. In this paper, recent advances of pulse coding methods used in DOFVS are reviewed, from pulse...
