Principle of FBG Fiber Bragg Grating Images
Fiber Bragg Gratings are made by laterally exposing the core of a single-mode fiber to a periodic pattern of intense laser light. The exposure produces a permanent increase in the refractive index of the fiber's core, creating a fixed index modulation according to the exposure. A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. These gratings are inscribed on optical fibers using different methods, creating what we call Fiber Bragg Gratings or FBG Sensors.
