Abstract

Optical fibres are the ideal sensing platform to measure strain, pressure, temperature, displacement, vibration, torsion, and humidity [1], thanks to their extreme environmental robustness. Since they are made of dielectric material, optical fibres are immune to electromagnetic interference and corrosion, are highly sensitive, and have a very wide operating temperature range. In addition, optical fibre-based sensors can be lightweight while providing easy integration into a wide variety of structures, while being low cost compared to an alternative approach. In particular, fibre Bragg gratings, polarization-maintaining fibres, and multicore fibres [2] are used as force or strain sensors in a broad range of industrial, medical, and military applications.
