1.5µm Brillouin-based fibre optic distributed temperature sensor with high spatial resolution of 20cm

Abstract

We demonstrate a high spatial resolution single-ended spontaneous Brillouin-based distributed temperature sensor for a 500m length of single-mode silica fibre. Using a short pulsewidth laser source at 1.5μm, measurements down to a spatial resolution of 20cm and temperature resolution of 4.4°C were achieved.
