The use of Fiber Bragg Grating (FBG) sensors is widespread due to its small diameter, light weight, high strength, high sensitivity, being non-electrical and their corrosive resistance. A broadband light is emitted from a source and the FBG reflects one narrow wavelength. Measuring the wavelength shift, it is possible to determine the deformation the fiber has undergone. This system is suitable for long-term monitoring as it does not need any extra maintenance.
