Phase-shift based BOTDA measurements tolerant to non-local effects
(SPIE, 2013) Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a BOTDA sensor based on the use of the Brillouin phase shift that performs measurements tolerant to non local effects. This technique raises opportunities to increase the distance covered by these sensors ...
Dynamic BOTDA measurements using Brillouin phase-shift
(SPIE, 2012) Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a novel dynamic BOTDA sensor based, for the first time to our knowledge, on the use of the Brillouin phase-shift instead of the conventional Brillouin gain. This provides the advantage of measurements that ...
