Event Discrimination Using Phase Correlation in Φ-OTDR System Based on Coherent Detection
We report a novel method of event discrimination using phase correlation in Φ-OTDR system based on coherent detection. The phase change demodulated from the Rayleigh backscattering light is the result of the event acting on the optical fiber. Then, the correlation coefficient between the...
