Application of remote power-by-light switching in a simplified BOTDA sensor network
(MDPI, 2013)
Artículo / Artikulua,
We propose and demonstrate the use of spatial multiplexing as a means to reduce the costs of distributed sensing networks. We propose a new scheme in which remote power-by-light switching is deployed to scan multiple ...
An in-reflection strain sensing head based on a Hi-Bi photonic crystal fiber
(MDPI, 2013)
Artículo / Artikulua,
A photonic crystal fiber-based sensing head is proposed for strain measurements. The sensor comprises a Hi-Bi PCF sensing head to measure interferometric signals in-reflection. An experimental background study of the sensing ...
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 ...
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 ...
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 ...
Simultaneous measurement of humidity and vibration based on a nanowire sensor system using Fast Fourier Transform technique
(IEEEOptical Society of America, 2016)
Artículo / Artikulua,
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 ...
Láseres de fibra óptica
(Versys, 2011)
Artículo / Artikulua,
Desde su desarrollo en los años 60 hasta nuestros días, los láseres de fibra óptica
han ido incrementando su importancia en diversos ámbitos de nuestra vida. Ya sea
en la medicina, la electrónica de consumo o la industria, ...
Comparison between capacitive and microstructured optical fiber soil moisture sensors
(MDPI, 2018)
Artículo / Artikulua,
Soil moisture content has always been an important parameter to control because it is a
deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection.
In this work, a discrete sensor ...
Long-range hybrid network with point and distributed Brillouin sensors using Raman amplification
(Optical Society of America, 2010)
info:eu-repo/semantics/article,
We propose a novel concept for hybrid networks that combine
point and distributed Brillouin sensors in a cost-effective architecture that
also deploys remote distributed Raman amplification to extend the sensing
range. A ...
Suspended-core fiber Sagnac combined dual-random mirror Raman fiber laser
(Optical Society of America, 2011)
info:eu-repo/semantics/article,
In the present work, a multiwavelength fiber laser based in the
combination of a double-random mirror and a suspended-core Sagnac
interferometer is presented. The double-random mirror acts by itself as a
random laser, ...
