Abstract
We report a commercially viable high spatial resolution, long range optical fiber distributed temperature sensor based on Brillouin scattering exploiting a low cost detection system. A spatial resolution of 3.0 meters with a Brillouin temperature resolution of 0.9 degree(s)C at a range of 16 km has been achieved.
