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. ...
Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors
(IEEE, 2017)
Artículo / Artikulua,
We present two techniques that provide an extension of the dynamic range of coherent Brillouin optical time-domain analysis (BOTDA) sensors for dynamic measurements. This type of BOTDA sensors rely on self-heterodyne ...
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 ...
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. ...
46-km-long Raman amplified hybrid double-bus network with point and distributed Brillouin sensors
(IEEE, 2012)
info:eu-repo/semantics/article,
We experimentally demonstrate a 46-km hybrid network that combine point and distributed Brillouin sensors. The proposed sensor network multiplexes low-cost intensity point sensors based on fiber-optic tapers, which are ...
Detrimental effects in Brillouin distributed sensors caused by EDFA transient
(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.
L-band multiwavelength single-longitudinal mode fiber laser for sensing applications
(IEEE / OSA, 2012)
info:eu-repo/semantics/article,
In this work, a novel single-longitudinal-mode (SLM) four-wavelength laser configuration for sensing applications in the L-band is proposed and experimentally demonstrated. The sensor system presented here is based on ring ...
Distributed dynamic strain sensing via perfect periodic coherent codes and a polarization diversity receiver
(IEEE, 2019)
info:eu-repo/semantics/article,
Rayleigh scattering-based dynamic strain sensing with high spatial resolution, fast update rate, and high sensitivity is highly desired for applications such as structural health monitoring and shape sensing. A key issue ...
Structural health monitoring of solar trackers using distributed fiber optic sensors
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
We demonstrate the application of a novel type of distributed fiber optic sensors (DFOSs) to dynamically monitor the effects of wind on solar tracker structures used in photovoltaic power stations. This DFOS is based on ...
