A fibre optic sensor capable of discriminating between temperature and strain, using a
single fibre Bragg grating, is presented. The technique exploits the core–cladding mode …

In this article, approaches reported in the literature for multi-parameter measurement relying
on fiber grating technology are reviewed. Due to its importance, the particular case of …

For accurate strain measurement by fiber Bragg grating (FBG) sensors, it is necessary to
compensate the influence of temperature change. In this study two devices using FBG …

We experimentally demonstrate a strain sensor realized using a twin-core photonic crystal
fiber (PCF). The strain sensor element consists of a 10 cm long in-fiber Mach–Zehnder …

We report on the analysis and experimental validation of the strain sensitivity dependences
of a fiber Bragg grating written in standard optical fiber when combined with fused tapers. By …

A dual cross-axis interference polarization-maintaining fiber interferometer (DCAI-PMFI) for
simultaneous measurement of strain and temperature is proposed. By using the cross …

We present a new bend sensor which can measure the curvature using an etched fiber
Bragg grating (FBG) embedded into a beam. The reflection power of the grating detected by …
