It is still a challenge to realize the absolute optical path difference (OPD) demodulation of the high-finesse fiber-optic Fabry-Perot (FP) sensors with a high resolution and high speed. This paper…
In this article, we propose a hybrid time and wavelength division multiplexed (TWDM) active quadrature demodulation technique for fiber-optic Fabry-Perot acoustic sensor network. A modulated gratin…
When the cavity changes during spectrum acquisition process, Doppler phenomena will occur and cause conventional scanning white-light interferometry (WLI) to fail. To absolutely demodulate the cavi…
Optical fiber hot-wire anemometer is an emerging technique for wind speed measurement. In many practical applications, both the magnitude and the direction of the flow need to be obtained. However,…
In this article, a tilted fiber Bragg grating (TFBG) plasmonic sensor based on thymine (T) - Hg - thymine (T) (T-Hg-T) base asymmetric pairing and Au nanoparticles (AuNPs), which can be used for hi…
Wavelength interrogation has been widely used for fiber-optic sensors based on Fabry-Perot interferometers (FPIs) because of its high measurement resolution. However, phase ambiguity often limits t…
