Paper Abstract

A technique is described whereby multipoint temperature measurements may simultaneously be made over long distances (up to 4 km) using a single optical fibre as the sensing element. The technique, which is based on the detection of Raman backscatter, utilizes a state-of-the-art photon-counting receiver plus a novel method for eliminating the effects of wavelength dependency in the fibre attenuation. A practical system is now in the final stages of development, based upon the use of 50/125 0.2NA multimode fibre, and a distance resolution of 1 m.
