Enhanced performance of long range Brillouin intensity based temperature sensors using remote Raman amplification
Enhanced performance of long range Brillouin intensity based temperature sensors using remote Raman amplification
We report on the use of remote Raman amplification to improve the accuracy of spontaneous Brillouin measurements for long range distributed sensor applications. The enhancement of the signal to noise was demonstrated in a long range distributed temperature sensor exploiting the temperature dependence of the spontaneous Brillouin backscattered signal. A temperature resolution of 8 °C and a spatial resolution of 20 m were obtained at a sensing range of 100 km. The Brillouin signal was averaged 2(20) times.

Abstract
We report on the use of remote Raman amplification to improve the accuracy of spontaneous Brillouin measurements for long range distributed sensor applications. The enhancement of the signal to noise was demonstrated in a long range distributed temperature sensor exploiting the temperature dependence of the spontaneous Brillouin backscattered signal. A temperature resolution of 8 °C and a spatial resolution of 20 m were obtained at a sensing range of 100 km. The Brillouin signal was averaged 2(20) times.
