摘要：Phase-sensitive optical time-domain reflectometry (Φ-OTDR), which utilizes the phase information of Rayleigh scattered lightwave inside optical fiber, could turn a fiber cable into a massive sensor array for distributed acoustic sensing (DAS), i. e., an emerging infrastructure for Internet of Things. Given a certain fiber length, there are trade-offs among the sensing bandwidth, the sensitivity and the spatial resolution. In this paper, the concept of linearization and Golay pulse-coding for heterodyne Φ-OTDR are proposed and experimentally verified for the first time. Firstly we gave a ...
