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