Meaning of FBG
Fiber Bragg gratings (FBGs) are a type of optical fiber sensor that utilizes the principles of light interference and fiber grating to measure physical parameters such as strain, temperature, and pressure. FBGs are formed by creating a periodic variation in the refractive index of an optical fiber, which causes light waves to reflect back at specific wavelengths. The reflected wavelength is sensitive to changes in the fiber’s physical properties, allowing FBGs to be used as highly accurate and versatile sensors. They find applications in various fields, including aerospace, civil engineering, and biomedical engineering.
