Application of remote power-by-light switching in a simplified BOTDA sensor network
(MDPI, 2013)
Artículo / Artikulua,
We propose and demonstrate the use of spatial multiplexing as a means to reduce the costs of distributed sensing networks. We propose a new scheme in which remote power-by-light switching is deployed to scan multiple ...
Monitorización de deformaciones y temperaturas en la estructura de un túnel artificial de alta velocidad mediante sensores ópticos puntuales, de longitud y distribuidos
(CSIC, 2015)
info:eu-repo/semantics/article,
La monitorización de estructuras es una rama de la ingeniería estructural que está captando mucha atención actualmente. Las deformaciones y temperaturas son, habitualmente, los parámetros monitorizados porque son los que ...
Swept optical single sideband modulation for spectral measurement applications using stimulated Brillouin scattering
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We propose a technique for the generation of broadband optical single sideband modulated signals. The technique is based on optically processing an optical double sideband signal using stimulated Brillouin scattering effect. ...
Orthogonally polarized optical single sideband modulation for microwave photonics processing using stimulated Brillouin scattering
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We present a novel technique to generate orthogonally polarized
optical single sideband modulated signals. The modulation scheme is based
on all optical stimulated Brillouin scattering processing of the optical carrier
of ...
Effects of pump pulse extinction ratio in Brillouin optical time-domain analysis sensors
(Optical Society of America, 2017)
info:eu-repo/semantics/article,
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 ...
Long-range hybrid network with point and distributed Brillouin sensors using Raman amplification
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We propose a novel concept for hybrid networks that combine
point and distributed Brillouin sensors in a cost-effective architecture that
also deploys remote distributed Raman amplification to extend the sensing
range. A ...
Linearly-configured BOCDA system with large modulation amplitude using dual-probe wave
(Optical Society of America, 2018)
Contribución a congreso / Biltzarrerako ekarpena,
We present and experimentally demonstrated a linearly-configured Brillouin optical correlation domain analysis (LC-BOCDA) system that allows large modulation amplitude (Δf) based on a dual probe wave and the control of ...
Second-order nonlocal effects mitigation in Brillouin optical time-domain analysis sensors by tracking the Brillouin frequency shift profile of the fiber
(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
(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 ...
Zuntz optikoan oinarritutako sentsoreen prestazioen muga-efektu berria, egituren egoera monitorizatzea helburu
(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. ...
