Quasi-distributed vibration sensing using OFDR and weak reflectors
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
The authors proposed a quasi-distributed vibration sensing technique using in-line weak reflectors and optical frequency domain reflectometry (OFDR). As a result, they achieved an 8 kHz measurable vibration frequency with ...
Quasi-distributed vibration sensing based on weak reflectors and STFT demodulation
(IEEE, 2020)
Artículo / Artikulua,
In this work, a new system is proposed for quasi-distributed vibration sensing based on the Doppler effect. The setup employs an optical frequency domain reflectometer (OFDR) and an array of weak reflectors. The short-time ...
Gamma radiation-induced effects over an optical fiber laser: towards new sensing applications
(MDPI, 2020)
info:eu-repo/semantics/article,
In the present work, the effect of gamma radiation on the performance of different types of erbium-doped fibers (EDFs) when they are used in a fiber ring cavity (FRC) configuration is studied. Several pieces of commercial ...
Wavelength converter using a highly Er-doped optical fiber ring laser
(IOP Publishing, 2018)
info:eu-repo/semantics/article,
This work presents an all-fiber wavelength converter based on a highly Er-doped fiber laser, which has been experimentally demonstrated. Frequencies from several kilohertz up to tens of gigahertz have been investigated. ...
Enhancement of the sensitivity of a volatile organic compounds MOF sensor by means of its structure
(MDPI, 2019)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we experimentally compare several core structures of Microstructured Optical Fibers (MOFs) for low-finesse Fabry-Pérot (FP) sensors. These sensors are designed for Volatile Organic Compounds (VOCs) measurements. ...
Sensitivity optimization of a microstructured optical fiber ammonia gas sensor by means of tuning the thickness of a metal oxide nano-coating
(IEEE, 2019)
Artículo / Artikulua,
In this paper, the influence of the thickness of
metallic-oxide coatings, ITO, and SnO2 on the sensitivity of a
microstructured optical fiber Fabry–Pérot (FP) has been studied
with the aim of developing ammonia gas fiber ...
