Brillouin optical time-domain analyzer for extended sensing range using probe dithering and cyclic coding

Iribas Pardo, Haritz ; Loayssa Lara, Alayn ; Sauser, Florian; Llera, Miguel; Le Floch, Sébastien (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

Iribas Pardo, Haritz ; Loayssa Lara, Alayn ; Sauser, Florian; Llera, Miguel; Le Floch, Sébastien (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 ...
