Simplified Brillouin sensor for structural health monitoring applications based on passive optical filtering

Iribas Pardo, Haritz; Urricelqui Polvorinos, Javier; Mariñelarena Ollacarizqueta, Jon; Sagüés García, Mikel; Loayssa Lara, Alayn (SPIE, 2015) Contribución a congreso / Biltzarrerako ekarpena,

We present a simplified configuration for distributed Brillouin optical time domain analysis sensors. The technique is based on passive optical filtering of the spectral components generated in an RF-pulse-modulated optical ...

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 ...

Egituren egoeraren monitorizaziorako zuntz optikoan oinarritutako sentsore sinplifikatua

Iribas Pardo, Haritz; Sagüés García, Mikel; Mariñelarena Ollacarizqueta, Jon; Loayssa Lara, Alayn (Udako Euskal Unibertsitatea, 2015) 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 ...

Polarization diversity scheme for BOTDA sensors based on a double orthogonal pump interaction

Urricelqui Polvorinos, Javier; López Fernandino, Felipe; Sagüés García, Mikel; Loayssa Lara, Alayn (IEEE, 2015) Artículo / Artikulua,

We introduce a Brillouin optical time domain analysis (BOTDA) sensor deploying a novel polarization diversity technique based on the use of two orthogonal pump pulses which simultaneously interact with a phase modulated ...

Overcoming non-local effects and Brillouin threshold limitations in Brillouin optical time domain sensors

Ruiz Lombera, Rubén; Urricelqui Polvorinos, Javier; Sagüés García, Mikel; Mirapeix, Jesús; López Higuera, José Miguel; Loayssa Lara, Alayn (IEEE, 2015) Artículo / Artikulua,

We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis (BOTDA) sensor that is able to operate with a probe power larger than the Brillouin threshold of the deployed sensing fiber ...

We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis sensor that is able to operate with a probe power larger than the Brillouin threshold of the deployed sensing fiber and that ...

Brilloun optical time domain analysis sensor assisted by a Brillouin distributed amplifier

Urricelqui Polvorinos, Javier; Sagüés García, Mikel; Loayssa Lara, Alayn (SPIE, 2015) Contribución a congreso / Biltzarrerako ekarpena,

We demonstrate the extension of the measurement range of Brillouin optical time-domain analysis (BOTDA) sensors using a distributed Brillouin amplifier (DBA). The technique is based on injecting a DBA pump wave in the ...
