100km distributed temperature sensor based on coherent detection of spontaneous Brillouin back-scatter
100km distributed temperature sensor based on coherent detection of spontaneous Brillouin back-scatter
We report the longest distributed temperature sensor based on microwave heterodyne detection of the frequency of the anti-Stokes Brillouin signal. At a sensing range of 100km, the temperature accuracy was 8degC, with a spatial resolution of 50m.

Abstract
We report the longest distributed temperature sensor based on microwave heterodyne detection of the frequency of the anti-Stokes Brillouin signal. At a sensing range of 100km, the temperature accuracy was 8degC, with a spatial resolution of 50m.
