Description/Abstract

We report a compact, portable optical fiber distributed temperature sensor based on spontaneous Brillouin backscattered light. The ratio of the Rayleigh and Brillouin backscattered light is known as the Landau-Placzek ratio and gives a measure of temperature. To measure the Landau-Placzek ratio the Rayleigh and Brillouin signals that are separated by a frequency of approximately 10 GHz have to be spectrally resolved. A narrow linewidth Q-switched fiber laser and an inexpensive low loss in-fiber Mach-Zehnder interferometer were developed for this purpose.
