Overcoming non-local effects and Brillouin threshold limitations in Brillouin distributed sensors
(SPIE, 2015) Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis sensor that is able to operate with a probe power larger than the Brillouin threshold of the deployed sensing fiber and that ...
Synthesis of virtual Brillouin frequency shift profiles in BOTDA sensors using optical source dithering
(SPIE, 2014) Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a novel concept for Brillouin optical time domain analysis sensors that is based on synthesizing a virtual Brillouin frequency shift profile along the sensing fiber. The technique is based on modulating the ...
