Low cutoff wavelength etched SMS structures towards verification of the quality of automotive antifreeze
(IEEE, 2020)
Artículo / Artikulua,
Optical fiber single mode-multimode-single mode (SMS) structures can be used as wavelength detection-based sensors. In this work, we focus on the performance at short wavelengths, where optical sources and detectors are ...
Optical fiber vacuum sensor based on etched SMS structure and PDMS coating
(IEEE, 2020)
info:eu-repo/semantics/article,
In this work, an optical fiber vacuum sensor based on a single-mode multimode single-mode (SMS) structure coated with polydimethylsiloxane (PDMS) is studied. The SMS structure generates an interferometric pattern based on ...
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 ...
