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 ...
Egituren egoeraren monitorizaziorako zuntz optikoan oinarritutako sentsore sinplifikatua
(Udako Euskal Unibertsitatea, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
Brillouin hedatuko denbora eremu optikoaren analisian (BOTDA) oinarritutako sentsoreak,
estruktura handien (100 km luzerako estrukturak) deformazioa eta tenperatura neurtzeko gaitasuna
dute. Lan honetan, BOTDA konfigurazio ...
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 ...
