The Bragg Networks are fiber optic sensors to measure deformations, vibrations, temperature, inclination and other parameters.
A Bragg network is a periodic or pseudo-periodic perturbation of the effective refractive index in the core of a fiber-optic.
The perturbation is usually approximately periodic in a certain length of, for example, a few millimetres or centimetres, and the period is around hundreds of nanometres.
Properties of the Bragg technology:
The use of Bragg sensors (FBG Fiber Bragg Grattings) has the following characteristics:
