Abstract :
We demonstrate a scheme which allows for temperature-corrected distributed strain measurements with improved spatial and strain resolutions and reduced data collection time. The technique utilizes the combination of frequency-based Brillouin optical correlation domain analysis with Brillouin intensity measurements for a fully temperature-compensated strain sensor with a strain resolution of 56 με and spatial and temperature resolutions of 10 cms and 0.95 °C.
