Technique for measuring distributed temperature with 35cm spatial resolution utilising the Landau-Placzek ratio

Technique for measuring distributed temperature with 35cm spatial resolution utilising the Landau-Placzek ratio
Technique for measuring distributed temperature with 35cm spatial resolution utilising the Landau-Placzek ratio
The authors report a spontaneous Brillouin-based distributed temperature sensing (DTS) system using a short-pulsewidth laser source at 1.5µm, which permits measurements down to an accuracy of 35cm spatial resolution. This DTS system has been demonstrated utilizing conventional single-mode silica fibers for a range of 1km from a single-ended source, and a temperature resolution of 4.3°C was achieved

Abstract

The authors report a spontaneous Brillouin-based distributed temperature sensing (DTS) system using a short-pulsewidth laser source at 1.5µm, which permits measurements down to an accuracy of 35cm spatial resolution. This DTS system has been demonstrated utilizing conventional single-mode silica fibers for a range of 1km from a single-ended source, and a temperature resolution of 4.3°C was achieved
