Optical fibers have been involved in the area of sensing applications for more than four
decades. Moreover, interferometric optical fiber sensors have attracted broad interest for …

Fiber Bragg Grating (FBG) sensors are among the most popular elements for fiber optic
sensor networks used for the direct measurement of temperature and strain. Modern FBG …

We present a multiplexed fibre Fizeau interferometer (FFI) and fibre Bragg grating (FBG)
sensor system for simultaneous measurement of quasi-static strain and temperature. A …

An optical fiber Fabry-Perot interferometer (FFPI) is proposed and demonstrated for dynamic
measurements in a mechanical vibrating target. A polishing metal with a low reflectance …

A demodulation algorithm for spatial-frequency-division-multiplexed fiber-optic Fizeau strain
sensor networks with a large number of sensors is proposed to effectively reduce the cross …

This paper develops a full three-dimensional finite element model in order to study the
vibrational behavior of a beam with a non-propagating surface crack. In this model, the …

In this study, speckle-visibility spectroscopy is used to measure the time-resolved particle
dynamics in the passive layer of a continuous granular flow in a half-full rotating drum. A …

In this study, we propose a new optical fiber interferometer based on differential structure.
The phase delay exists in the two output arms of the coupler. When the interference signal …

We report a relatively innovative method for automated fringe counting of a dual-cavity
extrinsic fiber Fabry-Perot interferometer for vibration measurements based on the …

In the case of multiple fringes and complex frequency measurements, the frequency of the
output signal changes rapidly when the vibration changes and frequency breakdown takes …
