Gain dependence of measured spectra in coherent Brillouin optical time-domain analysis sensors
(SPIE, 2016) Contribución a congreso / Biltzarrerako ekarpena,
We report on the effects of large pump pulse powers on Brillouin optical time-domain analysis (BOTDA) sensors based on phase-modulated probe wave and coherent detection. It is found that the large Brillouin gain that comes ...
Dual-probe linearly-configured BOCDA system with enlarged modulation amplitude
(Optical Society of America, 2018) Contribución a congreso / Biltzarrerako ekarpena,
We present and experimentally demonstrated a linearly-configured Brillouin optical correlation domain analysis (LC-BOCDA) system that allows large modulation amplitude (Δf) based on a dual probe wave and the control of ...
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 ...
