Abstract
We report on a novel experimental setup for distributed measurement of temperature, based on spontaneous Brillouin scattering in optical fiber. We have developed a mode-locked Brillouin fiber ring laser in order to generate the dual frequency source required for a heterodyne detection of the backscattered signal, This relatively simple system enables temperature measurements over 20 km with a spatial resolution of 7 m.
