This paper presents a comprehensive critical review of technologies used in the
development of fibre optic shape sensors (FOSSs). Their operation is based on multi …

One of the current frontier of optical fiber sensors, and a unique asset of this sensing
technology is the possibility to use a whole optical fiber, or optical fiber device, as a sensor …

The aim of this paper is to provide a comprehensive review of mode-division and spatial-
division optical fiber sensors, mainly encompassing interferometers and advanced fiber …

This paper presents the development of a three-dimensional (3-D) displacement sensor
based on one fiber Bragg grating (FBG). In order to obtain higher sensitivity and dynamic …

Multi parameter measurement based on optical fiber sensor has been a research hotspot in
recent years. In this work, four kinds of optical fiber sensors, LPFG, FBG, PMF and SMS are …

We demonstrated a two-dimensional vector-bending sensor by use of fiber Bragg gratings
(FBGs) inscribed in a homogeneous seven-core fiber. Seven FBGs were simultaneously …

Fiber Bragg gratings (FBGs) are inherently sensitive to temperature, axial strain, and
pressure, which can be easily measured by a shift of the Bragg wavelength in their …

The incidence of light on the edge of a glass coverslip for a microscope slide, deposited with
a thin film on both faces, permits exciting two resonances in each polarisation state of the …

We demonstrate a fiber-optic 3D vector displacement sensor based on the monitoring of
Bragg reflection from an eccentric grating inscribed in a depressed-cladding fiber using the …

We introduce a novel multiplexing technique applied to optical fiber distributed sensors,
based on optical backscatter reflectometry (OBR) and high-scattering MgO-doped fibers. In …
