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 ... -
Cyclic coding for Brillouin optical time-domain analyzers using probe dithering
Iribas Pardo, Haritz ; Loayssa Lara, Alayn ; Sauser, Florian; Llera, Miguel; Le Floch, Sébastien (Optical Society of America, 2017)
Artículo / Artikulua
We study the performance limits of mono-color cyclic coding applied to Brillouin optical time-domain analysis (BOTDA) sensors that use probe wave dithering. BOTDA analyzers with dithering of the probe use a dual-probe-sideband ... -
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 ...
