摘      要：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 *** experimental system of Stokes temperature sensor is set up and 2 km of operating length,1 m of distance resolution ,accuracy of ±0.1℃ are obtained.
