Abstract: Phase sensitive optical time domain reflectometry (Phase-OTDR) based distributed acoustic sensing systems have applications in structural health monitoring, perimeter security, oil and gas monitoring. These systems employ a fiber optic cable as the sensing element and obtain the spatial distribution by using highly coherent optical pulses from an optical interrogator. In this talk, the physics behind the Phase-OTDR systems, the technical challenges and the development of a commercial product will be discussed.
