22-km distributed temperature sensor using Brillouin gain in an optical fiber.

X Bao, D J Webb, D A Jackson.   

Abstract

We describe an experimental distributed temperature sensor that uses the temperature dependence of the Brillouin frequency shift. When a 22.2-km sensing length is used, we have observed a temperature resolution of 1 degrees C and have obtained a spatial resolution of 10 m.
