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 ...

Overcoming non-local effects and Brillouin threshold limitations in Brillouin distributed sensors

Urricelqui Polvorinos, Javier; Ruiz Lombera, Rubén; Sagüés García, Mikel; Mirapeix, Jesús; López Higuera, José Miguel; Loayssa Lara, Alayn (SPIE, 2015) Contribución a congreso / Biltzarrerako ekarpena,

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 ...

Dynamic BOTDA measurements based on Brillouin phase-shift and RF demodulation

Urricelqui Polvorinos, Javier; Zornoza Indart, Ander; Sagüés García, Mikel; Loayssa Lara, Alayn (Optical Society of America, 2012) Artículo / Artikulua,

We demonstrate a novel dynamic BOTDA sensor based, for the first time to our knowledge, on the use of the Brillouin phase shift in addition to the conventional Brillouin gain. This provides the advantage of measurements ...

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 ...

Zuntz optikoan oinarritutako sentsoreen prestazioen muga-efektu berria, egituren egoera monitorizatzea helburu

Iribas Pardo, Haritz; Mariñelarena Ollacarizqueta, Jon; Loayssa Lara, Alayn (Udako Euskal Unibertsitatea, 2017) Contribución a congreso / Biltzarrerako ekarpena,

Brillouin denbora-eremu optikoaren analisian (BOTDA) oinarritutako sentsoreak estruktura handien (120 km luzerako estrukturak) deformazioa eta tenperatura neurtzeko gaitasuna dute, metro bateko bereizmen espazialarekin. ...

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.

Second-order nonlocal effects mitigation in Brillouin optical time-domain analysis sensors by tracking the Brillouin frequency shift profile of the fiber

Mompó Roselló, Juan José; Iribas Pardo, Haritz; Urricelqui Polvorinos, Javier; Loayssa Lara, Alayn (IEEE, 2017) Artículo / Artikulua,

We report on an additional limitation that has been found in Brillouin optical time-domain analysis (BOTDA) sensors due to the so-called second-order nonlocal effects (NLE). Second-order NLE appear in BOTDA setups that ...

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 ...
