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 ...
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 ...
