Home / What is used to measure fiber optic grating displacement
An optical fiber sensing method based on a reflective grating panel is demonstrated for lateral displacement measurement. The fiber optic measurement technology for parameters apart from the main applications of strain and temperature is based exclusively on the technology of the fiber bragg grating (FBG). FBGs are created by exposing the fiber to a periodic pattern of intense UV radiation at a specific position of. Fiber Bragg grating technology is popularly used in measurements of various physical parameters, such as pressure, temperature, and strain for civil engineering, industrial engineering, military, maritime, and aerospace applications.
