Cost-effective Brillouin optical time-domain analysis sensor using a single optical source and passive optical filtering
(Hindawi Publishing Corporation, 2016)
Artículo / Artikulua,
We present a simplified configuration for distributed Brillouin optical time-domain analysis sensors that aims to reduce the cost of the sensor by reducing the number of components required for the generation of the two ...
Phasorial DPP-BOTDA sensor tolerant to non-local effects
(SPIE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
We introduce a modification of the differential pulse width pair technique in a BOTDA sensor based on a phase modulated probe wave and RF demodulation. This provides a differential Brillouin phasorial signal with high ...
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 ...
