In-field torsion measurements on solar trackers using fiber optic sensors
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
In-field torsion measurements on solar trackers using fiber Bragg gratings are presented. 45 FBG sensors have been deployed in an operational solar energy plant to study the mechanical response of the structure to wind.
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
