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 ...
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 ...
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 ...
Fiber optic sensor networks
(Elsevier, 2013)
info:eu-repo/semantics/article,
One of the main goals in fiber optic sensor technology is to multiplex together a high number of sensorsin the same network in order to share expensive terminal equipment and develop a system including multiple measuring ...
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 ...
Simultaneous measurement of humidity and vibration based on a microwire sensor system using Fast Fourier Transform technique
(IEEE, 2016)
info:eu-repo/semantics/article,
This paper presents a new sensor system for vibration and relative humidity measurements based on its interaction with the evanescent field of a microwire. The interrogation of the sensing head is carried out by monitoring ...
Remote (250 km) fiber Bragg grating multiplexing system
(MDPI, 2011)
Artículo / Artikulua,
We propose and demonstrate two ultra-long range fiber Bragg grating (FBG) sensor interrogation systems. In the first approach four FBGs are located 200 km from the monitoring station and a signal to noise ratio of 20 dB ...
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 ...
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 ...
