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 r...
