.Demodulated method of optical fiber stokes temperature sensors[J].Optoelectronics Letters,2006,2(5):345-347 Demodulated method of optical fiber stokes temperature sensors Abstract:       Based on the Stokes signals of the spontaneous Raman backscattering, a demodulated method for the simultaneous distributed temperature measurement in an optical fiber is presented to improve the sensitivity of the sensor. The experimental system of Stokes temperature sensor is set up and 2 km of operating length, 1 m of distance resolution, accuracy of ±0.1°C are obtained.
