Liquid level sensor based on dynamic Fabry–Perot interferometers in processed capillary fiber
(Springer Nature, 2021)
info:eu-repo/semantics/article,
In this work, a novel optical fiber sensor capable of measuring both the liquid level and its refractive
index is designed, manufactured and demonstrated through simulations and experimentally. For
this, a silica capillary ...
Spatial-frequency multiplexing of high-sensitivity liquid level sensors based on multimode interference micro-fibers
(Elsevier, 2020)
info:eu-repo/semantics/article,
This paper shows a new fiber optic sensor multiplexed system for liquid level sensing. Biconical fibertapers converging at a 40 mm-long micro-fiber are used as transducers. The tapers are designed to providethe propagation ...
Random DFB fiber laser for remote (200 km) sensor monitoring using hybrid WDM/TDM
(IEEE, 2016)
info:eu-repo/semantics/article,
In this paper, a random distributed feedback fiber laser is proposed as a multiplexing scheme for ultralong range measurements (up to 200 km). Optical fiber sensors are time and wavelength multiplexed overcoming one of the ...
Random fiber lasers: application to fiber optic sensors networks
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Recently, random mirrors have been proposed as a method to create fiber laser cavities. This kind of cavity is based on cooperative Rayleigh scattering, which is generated along a fiber due to the material inhomogeneities ...
All-PM fiber loop mirror interferometer analysis and simultaneous measurement of temperature and mechanical vibration
(IEEE, 2018)
info:eu-repo/semantics/article,
In this work, a new all-polarization maintaining (PM) fiber loop mirror interferometer is proposed and validated as temperature and mechanical vibration sensor. The scheme employs the arms of a PM coupler as communication ...
Optical power-based interrogation of plasmonic tilted fiber Bragg grating biosensors
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
Two interrogation techniques for plasmonic tilted fiber Bragg grating sensors are reported and experimentally tested. Typical interrogation methods are usually based on tracking the wavelength shift of the most sensitive ...
Real-time FFT analysis for interferometric sensors multiplexing
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this paper, a theoretical and experimental study of two interferometric sensor multiplexing schemes has been carried out by means of the fast Fourier transform (FFT) analysis. This work addresses one of the main drawbacks ...
Multiparameter sensor based on a multiinterferometric serial configuration for temperature and strain measurements
(IEEE, 2021)
Artículo / Artikulua,
In this work, a multi-parameter point sensor based
on the combination of Fabry-Perot (FP) and the anti-resonant
(AR) reflecting guidance in cascade configuration is proposed and
experimentally demonstrated. This structure, ...
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 ...
