Simplified Brillouin sensor for structural health monitoring applications based on passive optical filtering
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
We present a simplified configuration for distributed Brillouin optical time domain analysis sensors. The technique is based on passive optical filtering of the spectral components generated in an RF-pulse-modulated optical ...
Enhanced tolerance to pulse extinction ratio in Brillouin optical time domain analysis sensors by dithering of the optical source
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate the relaxation of the stringent requirements placed on the pulse extinction ratio in long-range Brillouin optical time-domain analysis sensors (BOTDA) by modulating the wavelength of the laser source that ...
