Working principle of fiber optic grating detectors
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 review provides a comprehensive overview of FBG sensor technology. Quartz is the main material that makes up fiber optic, consisting of a core and a cladding layer. The outer layer is protected by a coating layer.
