57km single-ended spontaneous Brillouin-based distributed fiber temperature sensor using microwave coherent detection

57km single-ended spontaneous Brillouin-based distributed fiber temperature sensor using microwave coherent detection
57km single-ended spontaneous Brillouin-based distributed fiber temperature sensor using microwave coherent detection
We present a novel technique for performing single-ended distributed fiber temperature measurements by use of microwave heterodyne detection of spontaneous Brillouin scattering. Brillouin frequency-shift measurements were obtained for a sensing length of 57km, with a spatial resolution of 20m. The rms error in frequency measurements at the far end of the sensing fiber was less than 3MHz, and the overall frequency dependence on temperature was 1.07±0.06 MHz/K.

Abstract

We present a novel technique for performing single-ended distributed fiber temperature measurements by use of microwave heterodyne detection of spontaneous Brillouin scattering. Brillouin frequency-shift measurements were obtained for a sensing length of 57km, with a spatial resolution of 20m. The rms error in frequency measurements at the far end of the sensing fiber was less than 3MHz, and the overall frequency dependence on temperature was 1.07±0.06 MHz/K.
