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.
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 ...
Traffic monitoring based on FBG sensor arrays in asphalt structures
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
We evaluate the capabilities of optical fiber sensors to measure traffic flow, speed, weight estimation and pavement degradation. The proper operation of the system has been proved 3.5 years after the installation in a ...
WDM and TDM interrogation by sequentially pulsing direct modulated DFBs
(Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
A new versatile and cost-effective interrogation system by pulsing direct modulated (DM) DFB laser diodes is proposed. 1 pm wavelength resolution and 600 m sensor spacing is demonstrated by sequentially pulsing a DM DFB.
