Brillouin optical time-domain analyzer for extended sensing range using probe dithering and cyclic coding
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We present an enhanced performance Brillouin optical time-domain analysis sensor that uses dual probes waves with optical frequency modulation and cyclic coding. The frequency modulation serves to increase the probe power ...
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 ...
