In this paper, a novel deep learning characterization approach is proposed and demonstrated experimentally using a pressure sensor based on a Sagnac interferometer realized by a side-hole fiber. To…
This paper proposes a new approach of demodulating the spectra of tilted fiber Bragg grating (TFBG) based refractive-index (RI) sensor by employing convolutional neural networks (CNN) with residual…
This paper presents a new method of demodulating the spectrum of fiber Bragg grating (FBG) based sensors by employing deep convolutional neural networks (DCNN). As a proof of demonstration, FBG-bas…
Distributed acoustic sensing is a recently developed technique that has demonstrated its utility in vibration and strain detection. However, for conventional demodulating algorithm, the dynamic ran…
Optical fiber gratings inscribed on polymer fibers are more versatile compare with those in silica fibers due to the diversity of the polymers. However the present polymer fiber gratings have weak …
We demonstrated an all-fiber 2-D inclinometer based on fiber Bragg gratings with the capability of measuring the azimuthal angle and the inclination angle, simultaneously. The sensor performance is…
