Brillouin and Rayleigh Signal Discrimination by Means of a π-Phase-Shifted Bragg Grating for Distributed Temperature Sensing

ABSTRACT

We report a novel technique to separate Brillouin and Rayleigh scattered light in order to generate the Landau-Placzek ratio required for distributed temperature sensing.
