Fiber Bragg gratings sensors are excellent sensing elements for measuring static and dynamic fields, such as temperature, strain, and pressure. The measured value is wavelength encoded, that is the central wavelength of the grating is dependent on the measured value. These sensors are independent of the power sources and connector losses. And using these in-fiber sensors gives the ability to multiplex many of them into one single mode fiber, which is called sensor array. All the advantages of the fiber are also advantages for this type of sensors such as immunity to the electromagnetic interference (EMI) and high radiation environment, lightweight, flexibility, stability and high temperature tolerance. The small size of the fiber diameter makes it suitable for sensing where small sensors are required. Moreover, its response is linear from part per million to a few percentage, which is much larger than strain gauge sensors. Civil engineers are also using this type of sensors to monitor strain in a structure, and to find the damage point for a structure by embedding it inside the material. Fiber grating sensors are also used in the process control and aerospace industries.
