Abstract
An automated distributed sensor system based on Brillouin scattering has been developed for temperature and strain measurement. This system can provide centimetre spatial resolution for simultaneous temperature and strain sensing with strain accuracy of 10-30 με and temperature accuracy of 1-2°C using polarization maintained fibres (PMF) and photonic crystal fibres (PCF). We used this sensor to detect a 1.5 cm crack in an optical ground wire.
