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 ... -

Iribas Pardo, Haritz; Urricelqui Polvorinos, Javier ; Mariñelarena Ollacarizqueta, Jon ; Sagüés García, Mikel ; Loayssa Lara, Alayn (Hindawi Publishing Corporation, 2016)
Artículo / Artikulua
We present a simplified configuration for distributed Brillouin optical time-domain analysis sensors that aims to reduce the cost of the sensor by reducing the number of components required for the generation of the two ... -
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 ... -
Effects of pump pulse extinction ratio in Brillouin optical time-domain analysis sensors
Iribas Pardo, Haritz; Mariñelarena Ollacarizqueta, Jon ; Feng, Cheng; Urricelqui Polvorinos, Javier ; Schneider, Thomas; Loayssa Lara, Alayn (Optical Society of America, 2017)
Artículo / Artikulua
We report on two previously unknown non-local effects that have been found to impair Brillouin optical time-domain analysis (BOTDA) sensors that deploy limited extinction ratio (ER) pump pulses. The first one originates ... -
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 ... -
