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 ... -
Detrimental effects in Brillouin distributed sensors caused by EDFA transient
Feng, Cheng; Iribas Pardo, Haritz ; Mariñelarena Ollacarizqueta, Jon ; Schneider, Thomas; Loayssa Lara, Alayn (Optical Society of AmericaIEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena
We investigate the deleterious effect and the error in Brillouin optical time-domain analyzers induced by the combination of a low extinction ratio pulse generation with the transient behavior of erbium-doped fiber amplifiers. -
Egituren egoeraren monitorizaziorako zuntz optikoan oinarritutako sentsore sinplifikatua

Contribución a congreso / Biltzarrerako ekarpena
Brillouin hedatuko denbora eremu optikoaren analisian (BOTDA) oinarritutako sentsoreak, estruktura handien (100 km luzerako estrukturak) deformazioa eta tenperatura neurtzeko gaitasuna dute. Lan honetan, BOTDA konfigurazio ... -
Enhanced tolerance to pulse extinction ratio in Brillouin optical time domain analysis sensors by dithering of the optical source
Iribas Pardo, Haritz ; Urricelqui Polvorinos, Javier ; Sagüés García, Mikel ; Loayssa Lara, Alayn (SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena
We demonstrate the relaxation of the stringent requirements placed on the pulse extinction ratio in long-range Brillouin optical time-domain analysis sensors (BOTDA) by modulating the wavelength of the laser source that ... -
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 ... -
Second-order non-local effects mitigation in BOTDA sensors by tracking the BFS profile
Mompó Roselló, Juan José; Iribas Pardo, Haritz ; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena
We demonstrate a technique to mitigate the residual second-order non-local effects in Brillouin optical time-domain analysis (BOTDA) sensors in which the Brillouin frequency shift (BFS) profile is not uniform along the ... -
