How is fiber Bragg grating velocities measured
The fundamental principle behind the operation of an FBG is, where light traveling between media of different refractive indices may both and at the interface. The values measured by the optical interrogator (data acquisition system) are the peak wavelengths of the narrow spectrum reflected by the fiber Bragg grating sensor. A fiber Bragg grating is a small length of optical fiber that comprises a pattern of many reflection points that creates a reflection of particular wavelengths of incident light.
