In this paper, a high sensitive fiber-optic Fabry-Perot interferometer sensor based on gold
diaphragm for acoustic detection has been proposed and experimentally demonstrated. The …

Acoustic sensing and monitoring are important techniques for structural health monitoring,
marine exploration, biomedicine, etc. In contrast to conventional electrical acoustic sensors …

In this study, a compact fiber-optic ultrasonic sensor based on a tapered multi-core fiber
(TMCF) is proposed and experimentally demonstrated. Comparative analysis and …

Special equipment is prone to crack damage due to long-term pressure bearing during
service. If the cracks in the structure are not detected in time and maintenance work is …

The sensitivity of an accelerometer-based on fiber Bragg grating (FBG) is limited by the
stiffness of the encapsulated fiber, and this article is inspired to research the highly sensitive …

A micro ultrasonic sensor based on an advanced suspended-core fiber is proposed and
employed for in-lab seismic physical modeling. A free suspended core is obtained by acid …

Because inclined cracks are more harmful to pressurized tanks than parallel cracks, the
existing ultrasonic testing methods cannot meet the needs of on-line monitoring for pressure …

A compact optical fiber Fabry–Perot interferometer is proposed and demonstrated for
ultrasound wave (UW) measurement. The sensor consists of a suspended cantilever in a …

An integrated endoscopic device is designed and employed for endoscopic ultrasonic
imaging of seismic physical models (SPMs). A graded-index-multimode-fiber-based Fabry …

The problem of three-dimensional (3D) acoustic scattering in a complex medium has
aroused considerable interest of researchers for many years. An ultrasonic scattered field …
