Detection Performance Improvement of Distributed Vibration Sensor Based on Curvelet Denoising Method
A curvelet denoising method has been proposed to reduce the time domain noise to improve the detection performance in the distributed fiber vibration sensing system based on phase-sensitive optical time domain reflectometry. The raw Rayleigh backscattering traces are regarded as a gray image and the...
