Paper Abstract

Distributed temperature sensors based on Brillouin scattering are attractive because they offer very large sensing length. The intensity of spontaneous Brillouin scattering is directly proportional to the temperature of the fiber, and permits a measurement independent of the strain applied to it. We report on a novel system to detect this signal, incorporating a mode-locked Brillouin fiber ring laser.
