Paper Abstract

A new fast demodulation technique for a quasi-distributed temperature sensor based on the interrogation of identical concatenated fibre Bragg gratings is presented. The interrogation scheme is based on the optical time domain reflectometry technique, for which a commercial device has been extended to a wavelength-tuneable system, within an automated experimental set-up. Detection and localization of an important amount of sensing points along a unique optical fibre is demonstrated. The demodulation method is based on the optimization of the least square differences between reference and measured data. Repeatability measurements and associated accuracy of the sensor are presented.
