Enhancement of signal-to-noise ratio in Brillouin optical time domain analyzers by dual-probe detection
(SPIE, 2017) Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a simple technique to enhance the signal-to-noise ratio (SNR) in Brillouin optical time-domain analysis sensors by the addition of gain and loss processes. The technique is based on the shift of the pump ...
