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 ...
Fully switchable multi-wavelength fiber lasers based on random distributed feedback for sensors interrogation
(IEEE / OSA, 2015)
info:eu-repo/semantics/article,
In this paper, the experimental study and characterization of a novel real-time switchable multi-wavelength fiber laser has been carried out. Two different gain materials, such as a 50 km SMF and a 2.5 km DCF fibers were ...
Micro-displacement sensor combined with a fiber ring interrogated by an optical time-domain reflectometer
(IEEE, 2014)
info:eu-repo/semantics/article,
A micro-displacement sensing head based on two aligned cleaved fibers inserted into an optical fiber ring and interrogated by an OTDR is presented. The sensor configuration is characterized for measuring both longitudinal ...
Internal modulation of a Random fiber laser
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A characterization of a modulated random mirror laser has been experimentally carried out. Unlike conventional internally modulated fiber lasers, no distortion of the modulating frequency or self-mode-locking effects were ...
250 km ultra long remote sensor system based on a fiber loop mirror interrogated by an OTDR
(Optical Society of America, 2011)
info:eu-repo/semantics/article,
A 253 km ultra long remote displacement sensor system based on a fiber loop mirror interrogated by a commercial OTDR is proposed and experimentally demonstrated. The use of a fiber loop mirror increases the signal to noise ...
