Spectral shadowing suppression technique in phase-OTDR sensing based on weak fiber Bragg grating array
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
A postprocessing procedure is presented to suppress spectral shadowing in phase-OTDR sensing systems based on a weak fiber Bragg grating array. A complete theoretical analysis of the interfering signals has been carried ...
Quasi-distributed vibration sensing using OFDR and weak reflectors
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
The authors proposed a quasi-distributed vibration sensing technique using in-line weak reflectors and optical frequency domain reflectometry (OFDR). As a result, they achieved an 8 kHz measurable vibration frequency with ...
Optical fiber lasers assisted by microdrilled optical fiber tapers
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
In this Letter, we present an analysis of the backscattering generated in a microdrilled tapered fiber within a short-linear-cavity fiber laser. We propose and experimentally demonstrate a fiber cavity laser based on a ...
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 ...
Sensitivity optimization of a microstructured optical fiber ammonia gas sensor by means of tuning the thickness of a metal oxide nano-coating
(IEEE, 2019)
Artículo / Artikulua,
In this paper, the influence of the thickness of
metallic-oxide coatings, ITO, and SnO2 on the sensitivity of a
microstructured optical fiber Fabry–Pérot (FP) has been studied
with the aim of developing ammonia gas fiber ...
Micro-drilled optical fiber for enhanced laser strain sensors
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work, we present an experimental measurement of temperature and strain sensitivities of a micro-drilled optical
fiber (MDOF). The MDOF consisted of a quasi-randomly distributed reflector along a single mode fiber ...
Multiplexing optical fiber Fabry-Perot interferometers based on air-microcavities
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors ...
Enhancement of the sensitivity of a volatile organic compounds MOF sensor by means of its structure
(MDPI, 2019)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we experimentally compare several core structures of Microstructured Optical Fibers (MOFs) for low-finesse Fabry-Pérot (FP) sensors. These sensors are designed for Volatile Organic Compounds (VOCs) measurements. ...
