Nowadays, condition-based maintenance (CBM) and fault diagnosis (FD) of rotating
machinery (RM) has a vital role in the modern industrial world. However, the remaining …

The fiber Bragg grating (FBG) sensor, which was developed over recent decades, has been
widely used to measure manifold static measurands in a variety of industrial sectors. Multiple …

Carbon fiber reinforced polymer (CFRP) laminates have been becoming primary structures
in the aerospace industry because of their high specific strength and stiffness. However …

Highly sensitive ultrasonic fiber-optic Bragg gratings (FBGs) have been used as acoustic
emission (AE) sensors in the non-destructive inspection (NDI) for analyzing damage …

Nonlinear ultrasonic technique that evaluates the growth of the barely visible fatigue crack in
metal is difficult to be achieved by conventional optical fiber sensor because of the critical …

Recently, the authors have proposed a remote acoustic emission (AE) measurement
configuration using a sensitive fiber-optic Bragg grating (FBG) sensor. In the configuration …

We applied a highly sensitive phase-shifted fiber-optic Bragg grating (PS-FBG) sensor with a
broad bandwidth to acoustic emission (AE) detection in a composite material. Based on AE …

Acoustic source localization (ASL) plays an important role in structural health monitoring
(SHM). The L-shaped sensor cluster (LSSC) is very convenient for ASL, and hence SHM …

A broadband fiber-optic acoustic sensing system is proposed and demonstrated, which is
configured by a fiber Bragg grating (FBG) and an erbium-doped fiber (EDF) ring laser. As the …

Acoustic emission (AE) testing and Lamb wave inspection techniques have been widely
used in non-destructive testing and structural health monitoring. For thin plates, the AEs …
