Quasi-distributed vibration sensing using OFDR and weak reflectors
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
The authors proposed a quasi-distributed vibration sensing technique using in-line weak reflectors and optical frequency domain reflectometry (OFDR). As a result, they achieved an 8 kHz measurable vibration frequency with ...
Spectral shadowing suppression technique in phase-OTDR sensing based on weak fiber Bragg grating array
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
A postprocessing procedure is presented to suppress spectral shadowing in phase-OTDR sensing systems based on a weak fiber Bragg grating array. A complete theoretical analysis of the interfering signals has been carried ...
Sensitivity optimization of a microstructured optical fiber ammonia gas sensor by means of tuning the thickness of a metal oxide nano-coating
(IEEE, 2019)
Artículo / Artikulua,
In this paper, the influence of the thickness of
metallic-oxide coatings, ITO, and SnO2 on the sensitivity of a
microstructured optical fiber Fabry–Pérot (FP) has been studied
with the aim of developing ammonia gas fiber ...
Optical fiber lasers assisted by microdrilled optical fiber tapers
(Optical Society of America, 2019)
info:eu-repo/semantics/article,
In this Letter, we present an analysis of the backscattering generated in a microdrilled tapered fiber within a short-linear-cavity fiber laser. We propose and experimentally demonstrate a fiber cavity laser based on a ...
