A Novel Distributed Vibration Sensor Based on Fading Noise Reduction in Multi-Mode Fiber

Multi-mode fiber (MMF) is used in a polarization-sensitive optical time domain reflectometer (OTDR) for vibration event location and spectrum analysis. The vibration events acting on MMF are considered to be the optical polarization state and phase diversifying process for fading noise reduction. In...
