Technique for measuring distributed temperature with 35cm spatial resolution utilising the Landau-Placzek ratio
H.H.Kee, G.P.Lees and T.P.Newson
The authors report a spontaneous Brillouin-based distributed temperature sensing (DTS) system using a short pulse width laser source at 1.5μm, which permits measurements down to an accuracy of 35cm spatial resolution. This DTS system has been demonstrated utilising conventional single-mode silica fibers for a range of 1km from a single-ended source, and a temperature resolution of 43°C was achieved.
