Fbg fiber grating reconfiguration
These types of gratings can be reconfigurable through special packaging and system design. Fiber Bragg grating (FBG) sensors have emerged as advanced tools for monitoring a wide range of physical parameters in various fields, including structural health, aerospace, biochemical, and environmental applications. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a. A variation of the period of the grating inscripted in a fiber optic – induced by mechanical or thermal perturbation – causes a shift of the reflected peak wavelength, due to the related optical path length variation.
