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.
Development of a water flow and velocity optical fiber sensor for field testing
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
