Principle of Fiber Bragg Grating Detection Circuit
This article explains the principle of Fiber Bragg Grating (FBG) sensors based on the fundamental concept of "reflection and interference of light waves," including the principles of temperature measurement, stress measurement, and strain measurement using FBGs. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a. In this Chapter we will concentrate on a very special type of OFS: the Fiber Bragg Grating (FBG) sensors.
