Optical fiber networks for remote fiber optic sensors
(MDPI, 2012)
Artículo / Artikulua,
This paper presents an overview of optical fiber sensor networks for remote sensing. Firstly, the state of the art of remote fiber sensor systems has been considered. We have summarized the great evolution of these systems ...
Design rules for lossy mode resonance based sensors
(Optical Society of America, 2012)
Artículo / Artikulua,
Lossy mode resonances can be obtained in the transmission spectrum of cladding removed
multimode optical fiber coated with a thin-film. The sensitivity of these devices to changes
in the properties of the coating or the ...
Fe-rich ferromagnetic wires for self-sensing materials
(IEEE, 2012)
Artículo / Artikulua,
The possibility of using Fe-rich wires in mechanical stress self-sensing materials is investigated. To this end, a retrieval technique aimed to characterize the high-frequency magnetoimpedance effect in ferromagnetic wires ...
Dynamic BOTDA measurements based on Brillouin phase-shift and RF demodulation
(Optical Society of America, 2012)
Artículo / Artikulua,
We demonstrate a novel dynamic BOTDA sensor based, for the first time to our knowledge, on the use of the Brillouin phase shift in addition to the conventional Brillouin gain. This provides the advantage of measurements ...
Optical fiber bus protection network to multiplex sensors: experimental validation of self-diagnosis
(IEEE, 2012)
info:eu-repo/semantics/article,
The experimental demonstration of a resilient wavelength division multiplexed (WDM) fiber bus network to interconnect sensors is reported. The network recovers operation after failures and it performs 'self-diagnosis', the ...
L-band multiwavelength single-longitudinal mode fiber laser for sensing applications
(IEEE / OSA, 2012)
info:eu-repo/semantics/article,
In this work, a novel single-longitudinal-mode (SLM) four-wavelength laser configuration for sensing applications in the L-band is proposed and experimentally demonstrated. The sensor system presented here is based on ring ...
Concrete beam bending test monitorization using a high strain fiber optic sensor
(IEEE / OSA, 2012)
info:eu-repo/semantics/article,
In this work the development of an 'eight-shape' fiber optic sensor for high strain measurement is experimentally demonstrated. This strain sensor is interrogated using a commercial optical time domain reflectometer through ...
46-km-long Raman amplified hybrid double-bus network with point and distributed Brillouin sensors
(IEEE, 2012)
info:eu-repo/semantics/article,
We experimentally demonstrate a 46-km hybrid network that combine point and distributed Brillouin sensors. The proposed sensor network multiplexes low-cost intensity point sensors based on fiber-optic tapers, which are ...
A comprehensive analysis of the absorption spectrum of conducting ferromagnetic wires
(IEEE, 2012)
Artículo / Artikulua,
A detailed analysis of the absorption spectrum of conductive ferromagnetic wires is presented. The absorption spectrum is computed from the solution to the scattering problem, and circuit models are formulated to clarify ...
Tapered single-mode optical fiber pH sensor based on lossy mode resonances generated by a polymeric thin-film
(IEEE, 2012)
Artículo / Artikulua,
Lossy mode resonances can be generated with certain polymeric nanostructures, such as those obtained with a multilayered assembly of poly(allylamine hydrochloride) and poly (acrylic acid). This coating is adsorbed by the ...
