Metal 3D printed D-Band waveguide to surface wave transition
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
The coupling efficiency between free space waves and surface waves is low, narrowband, or both. Highly efficient broadband (better than 20% fractional bandwidth) coupling from waveguide modes can be achieved through ...
Second-order non-local effects mitigation in BOTDA sensors by tracking the BFS profile
(SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a technique to mitigate the residual second-order non-local effects in Brillouin optical time-domain analysis (BOTDA) sensors in which the Brillouin frequency shift (BFS) profile is not uniform along the ...
Angle-susceptible sensing metasurface in terahertz regime
(EDP Sciences, 2018)
info:eu-repo/semantics/conferenceObject,
Nowadays thin-film coatings and structures are widely used in advanced industrial and scientific ap-plications that makes the tasks of thin-film sensing highly demanded in practice. Last decade, stimulated by progress in ...
SnO2-MOF-Fabry-Pérot humidity optical sensor system based on Fast Fourier transform technique
(SPIE, 2016)
info:eu-repo/semantics/conferenceObject,
In this paper, a new sensor system for relative humidity measurements based on a SnO2 sputtering deposition on a microstructured optical fiber (MOF) low-finesse Fabry-Pérot (FP) sensing head is presented and characterized. ...
High-resolution transversal load sensor using a random distributed feedback fiber laser
(SPIE, 2016)
info:eu-repo/semantics/conferenceObject,
In this work, a new application of random distributed feedback lasers to fiber optic sensing has been presented. The particular properties of these lasers, such as the lack of longitudinal modes and high stability, have ...
Modulated fiber ring laser and its application in high-sensitivity temperature sensors
(SPIE, 2016)
info:eu-repo/semantics/conferenceObject,
This work presents an experimental demonstration of a scheme based on an internally modulated fiber ring laser for high-sensitivity temperature sensing. The attained temperature resolution has been as low as ± 2pm even ...
Random fiber lasers: application to fiber optic sensors networks
(IEEE, 2017)
info:eu-repo/semantics/conferenceObject,
Recently, random mirrors have been proposed as a method to create fiber laser cavities. This kind of cavity is based on cooperative Rayleigh scattering, which is generated along a fiber due to the material inhomogeneities ...
Simulación acústica de un evento singular en un entorno abierto: el Tribunal de las Aguas de la Huerta de Valencia
(Sociedade Portuguesa de Acústica, 2020)
Contribución a congreso / Biltzarrerako ekarpena,
El Tribunal de las Aguas de la Huerta de Valencia, declarado Patrimonio Cultural Inmaterial de la
Humanidad en 2009 por la UNESCO, es la más antigua institución de justicia existente en Europa. Cada
jueves, bajo la gótica ...
Ultra-long (275 km) random distributed feedback fiber laser for remote sensor monitoring
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
An interferometric sensor located 275 km away from the monitoring station has been interrogated by a double-pumped random distributed feedback fiber laser, reaching the longest distance in fiber optic remote sensing reported ...
High sensitivity fiber-optic liquid level sensor using biconical tapered fibers
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A liquid level sensor is presented using a biconical tapered standard single-mode fiber, being its main characteristic an outstanding sensitivity for a low cost transducer. Temperature compensation is enabled with the same ...
