Quasi-distributed vibration analysis of a cantilever beam using OFDR and weak reflectors
(Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
This work evaluates the performance of a quasi-distributed in-line velocimeter based on OFDR and weak reflectors to measure vibration every 10 cm, using a cantilever beam under free-end damping and during an impact-hammer test.
Anomalous relative intensity noise transfer in ultralong random fiber lasers
(Optical Society of America, 2020)
info:eu-repo/semantics/article,
We present, for the first time, an experimental demonstration of RIN noise transfer dampening at low frequencies in random distributed feedback ultralong Raman fibre lasers based on conventional telecommunication fibres. ...
Quasi-distributed vibration sensing based on weak reflectors and STFT demodulation
(IEEE, 2020)
Artículo / Artikulua,
In this work, a new system is proposed for quasi-distributed vibration sensing based on the Doppler effect. The setup employs an optical frequency domain reflectometer (OFDR) and an array of weak reflectors. The short-time ...
Multiparameter sensor based on a multiinterferometric serial configuration for temperature and strain measurements
(IEEE, 2021)
Artículo / Artikulua,
In this work, a multi-parameter point sensor based
on the combination of Fabry-Perot (FP) and the anti-resonant
(AR) reflecting guidance in cascade configuration is proposed and
experimentally demonstrated. This structure, ...
