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 ...
Relative humidity multi-point optical sensors system based on Fast Fourier multiplexing technique
(SPIE, 2017)
info:eu-repo/semantics/conferenceObject,
In this paper, a new multipoint optical fiber system for relative humidity measurements based on Sn02-FP (Fabry-Pérot) sensing heads and an optical interrogator as single active device is presented and characterized. 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 ...
Simultaneous strain and temperature multipoint sensor based on microstructured optical fiber
(IEEE, 2018)
info:eu-repo/semantics/article,
In this paper, a new sensor system for simultaneous and independent multipoint strain and temperature measurements is presented. The interrogation of the sensing heads has been carried out by monitoring their FFT phase ...
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 ...
Resilient amplified double ring optical networks to multiplex optical fibre sensors
(IEEE / OSA, 2009)
info:eu-repo/semantics/article,
We report the experimental demonstration of two configurations of an amplified optical fibre double ring network for the multiplexing of sensors. The networks are designed to be inherently resilient to fibre failures because ...
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 ...
