Gain dependence of the phase-shift spectra measured in coherent Brillouin optical time-domain analysis sensors
(IEEE, 2016)
Artículo / Artikulua,
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 self-heterodyne detection. These sensors are particularly ...
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 ...
Pulse coding linearization for Brillouin optical time-domain analysis sensors
(Optical Society of America, 2018)
Artículo / Artikulua,
We introduce a simple method to extend the performance of pulse coding techniques in their application to Brillouin optical time-domain analysis sensors (BOTDA). It is based on applying a simple logarithmic processing on ...
Linearly-configured BOCDA system with large modulation amplitude using dual-probe wave
(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 ...
Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors
(IEEE, 2017)
Artículo / Artikulua,
We present two techniques that provide an extension of the dynamic range of coherent Brillouin optical time-domain analysis (BOTDA) sensors for dynamic measurements. This type of BOTDA sensors rely on self-heterodyne ...
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 ...
