Recent Advances in Phase-Sensitive Optical Time Domain Reflectometry (Ф-OTDR)

Abstract Phase-sensitive optical time domain reflectometry (Ф-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 acoustic sensing (DAS) based on the...
