Photonic crystal fibers for sensing applications
(Hindawi Publishing Corporation, 2012)
Artículo / Artikulua,
Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved features beyond what conventional optical fibers can offer. Due to their unique geometric structure, photonic crystal fibers ...
Robust fiber-optic sensor networks
(Springer, 2012)
Artículo / Artikulua,
The ability to operate despite failure will become increasingly important as the use of optical sensor networks grows, and the amount of sensing information to be handled by a sensor network is increasing, especially for ...
Remote-time division multiplexing of bending sensors using a broadband light source
(Hindawi Publishing Corporation, 2012)
Artículo / Artikulua,
This work experimentally demonstrates a remote sensing network which interrogates bending sensors using time-division multiplexing techniques and a broadband light source. The bending sensors are located 50 km away from ...
Micro-displacement sensor based on a hollow-core photonic crystal fiber
(MDPI, 2012)
Artículo / Artikulua,
A sensing head based on a hollow-core photonic crystal fiber for in-reflection measurement of micro-displacements is presented. The sensing structure takes advantage of the multimodal behavior of a short segment of hollow-core ...
Dual stage ytterbium doped fiber laser in MOPA configuration
(Bentham Open, 2012)
Artículo / Artikulua,
We report the experimental demonstration of an Ytterbium doped fiber laser (YDFL) composed by two stages in cascade. Two sorts of Ytterbium doped fiber (YDF) with different concentration have been used. A proper characterization ...
Low noise dual-wavelength erbium fiber laser in single-longitudinal-mode operation
(Springer, 2012)
info:eu-repo/semantics/article,
A new stable dual-wavelength fiber-ring laser
based on erbium-doped fiber amplification is reported. The
laser is based on ring resonators and employs fiber Bragg
gratings to select the operation wavelengths. The ...
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 ...
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 ...
