A fiber optic relative humidity (RH) sensor based on the tilted fiber Bragg grating (TFBG)
coated with graphene oxide (GO) film was presented. Amplitudes of the cladding mode …

We experimentally demonstrated a strain sensor based on fiber ring cavity laser with a
photonic crystal fiber (PCF) in-line Mach-Zehnder interferometer (MZI) structure, which is …

A compact and low cost optical fiber sensor by introducing higher order modes interference
with fiber twisting based on single-mode-multimode-single-mode structure is proposed and …

A Mach-Zehnder interferometer (MZI) based fiber axial micro-displacement sensor was
proposed. The MZI was constructed by a bowknot-type taper (BTT) combining with a fiber …

An efficient fiber-optic sensor based on a superstructure fiber Bragg grating (SFBG) for
simultaneous strain and temperature measurement is numerically and experimentally …

With the development in the exploitation of maritime resources, the structural health
monitoring (SHM) of offshore structures becomes necessary. This study focuses on …

Traditional electrical expendable bathythermograph (XBT) is designed to fall at a known rate
based on a great deal of experiments so that the depth of the temperature profile can be …

This study firstly proposes and experimentally demonstrates a phase demodulation method
with high sensitivity for interferometric fiber sensors (IFSs) on the basis of the fast Fourier …

In this paper, a novel dual-parameter measurement scheme using a long-period grating
(LPG) concatenated with polarization maintaining fiber (PMF) in a Sagnac loop was …

This paper introduces a novel technique to simultaneously measure temperature and strain
using a single 5 mm femtosecond laser-inscribed superstructure fiber Bragg grating (SFBG) …
