Abstract Phase-sensitive optical time domain reflectometry (?-OTDR) is an effective way to detect vibrations and acoustic waves with high sensitivity, by interrogating coherent Rayleigh backscattering light in sensing fiber. In particular, fiber-optic distributed (DAS) based on the ?-OTDR phase demodulation has been extensively studied widely used intrusion detection, borehole seismic acquisiti...
