COVID-19 is a new strain of highly contagious coronavirus, and at present, more than 221.4
million people have been infected with this virus, and the death toll exceeds 2793398. Early …

This paper presents an extrinsic Fabry–Perot interferometer-based optical fiber sensor
(EFPI) for measuring three-dimensional (3D) displacements, including interfacial sliding and …

A compact optical fiber pressure sensor is experimentally presented. It consists of a few
millimeter long section of a capillary optical fiber spliced between two single-mode fibers …

We present a method for large displacement measurement based on light rays interference.
Instead of fiber's end-face, we launched the light from the side of fiber using a LED-Belt (LB) …

A novel curvature sensor was proposed based on a dual-core photonic crystal fiber (PCF)
that was spliced between two single-mode fibers (SMFs). The sensor sensitivity was …

An optical fiber strain sensor with adjustable sensitivity is proposed and demonstrated. The
strain sensing setup employs a fiber optic Michelson interferometer (sensing element) and …

We propose and demonstrate a fiber surface plasmon resonance (SPR) curvature sensor
with the function of directional recognition by coating a metal film on one side of the fiber. By …

The tuning and switching of the wavelength laser emissions in optical fiber laser were
experimentally analyzed and demonstrated. The tuning and switching of the laser were …

In this work, a simple design and cost-effective displacement-curvature sensor based on
macro-bend single-mode fiber (SMF) is planned and demonstrated. The optical fiber sensor …
