Brillouin distributed sensing assisted by Brillouin amplification of pump pulses
(IEEE, 2014) Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate, for the first time to our knowledge, the extension of the measurement range of Brillouin distributed sensors (BDS) by using a distributed Brillouin amplifier (DBA) to compensate the attenuation of the ...
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 ...
