Compensation of nonlocal effects induced by the extinction ratio of pump pulses in Brillouin optical time-domain analysis sensors
(Optical Society of America, 2019)
Artículo / Artikulua,
We demonstrate a technique to compensate the nonlocal effects that appear in Brillouin optical time-domain analysis sensors when pump pulses with limited extinction ratio are deployed. These recently discovered nonlocal ...
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 ...
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 ...
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 ...
Monitorización de deformaciones y temperaturas en la estructura de un túnel artificial de alta velocidad mediante sensores ópticos puntuales, de longitud y distribuidos
(CSIC, 2015)
info:eu-repo/semantics/article,
La monitorización de estructuras es una rama de la ingeniería estructural que está captando mucha atención actualmente. Las deformaciones y temperaturas son, habitualmente, los parámetros monitorizados porque son los que ...
Non-local effects in Brillouin optical time-domain analysis sensors
(MDPI, 2017)
Artículo / Artikulua,
Brillouin optical time-domain analysis (BOTDA) sensors have great potential to provide distributed measurements of temperature and strain over large structures with high spatial resolution and measurement precision. However, ...
Second-order non-local effects mitigation in BOTDA sensors by tracking the BFS profile
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a technique to mitigate the residual second-order non-local effects in Brillouin optical time-domain analysis (BOTDA) sensors in which the Brillouin frequency shift (BFS) profile is not uniform along the ...
Orthogonally polarized optical single sideband modulation for microwave photonics processing using stimulated Brillouin scattering
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We present a novel technique to generate orthogonally polarized
optical single sideband modulated signals. The modulation scheme is based
on all optical stimulated Brillouin scattering processing of the optical carrier
of ...
Multi-tap complex-coefficient incoherent microwave photonic filters based on optical single-sideband modulation and narrow band optical filtering
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
We propose a novel scheme to implement tunable multi-tap
complex coefficient filters based on optical single sideband modulation and
narrow band optical filtering. A four tap filter is experimentally
demonstrated to ...
Measurement of polarization dependent loss, polarization mode dispersion and group delay of optical components using swept optical single sideband modulated signals
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
We introduce a novel method for high wavelength-resolution
measurement of polarization-averaged group delay, polarization dependent
loss and polarization mode dispersion of optical components using swept
optical single ...
