Optical fiber sensors for asphalt structures monitoring
(Optica Publishing Group, 2016)
Contribución a congreso / Biltzarrerako ekarpena,
A novel optical fiber installation method was explored for asphalt monitoring. Glassfiber polymer encapsulated SMF was installed in the intermediate and surface layers in order to study the strain sensitivity with a ...
Aluminum coated fiber optic sensor for enhancing flow rate measurement
(SPIE, 2023)
Contribución a congreso / Biltzarrerako ekarpena,
A water flow and velocity aluminum-coated Fiber Bragg Grating sensor system for open channels was designed,
simulated and tested. The sensing head was designed, ruggedized and customized to measure velocities at ...
Fiber optic mirror fabrication using general-purpose metallic pigments
(SPIE, 2023)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the potential of using general-purpose paints to fabricate highly reflective, low-cost optical mirrors is evaluated. The study shows that high-reflectivity mirrors can be created in standard single-mode fiber ...
Sistema de interrogación multi-sensor basado en multiplexación en longitud de onda y tiempo
(SEDOPTICA, 2021)
Contribución a congreso / Biltzarrerako ekarpena,
En este trabajo se propone un sistema de interrogación versátil y económico basada en la
generación de pulsos empleando la modulación directa de diodos láser DFB. Se ha demostrado
una resolución en longitud de onda de 1 ...
Medida de torsión en seguidores solares con sensores de fibra óptica
(SEDOPTICA, 2021)
Contribución a congreso / Biltzarrerako ekarpena,
En este trabajo se ha monitorizado la torsión sufrida por una estructura de seguidores solares
empleando sensores de fibra óptica. Estas medidas de campo se han obtenido con una
red de sensores formada por 45 redes de ...
Multicore fiber sensors for strain measurement towards traffic monitoring
(SPIE, 2023)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, two new interferometric sensors based on multicore optical fibers for the measurement of strain with the
ultimate goal of traffic monitoring are presented. The operating principle of each sensor relied on ...
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 ...
One-year analysis of road condition using FBG arrays
(SPIE, 2023)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, it is presented an analysis of FBG arrays installed in a public road. The arrays were installed in a newly paved urban road and were monitored for more than one year. The study evidences the permanent deformation ...
Enhanced optical fiber lasers and optical fiber sensors assisted by micro-drilled optical fibers
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
Enhanced OFS assisted by micro-drilled optical fibers acting as mirrors are
demonstrated. Strain sensitivity improved more than one order of magnitude in comparison
with FBG sensors using a 50 μm-waist micro-drilled taper ...
