Large structure monitoring is one of the most active fields of fiber grating sensors. The measurement of mechanical parameters is very important for the maintenance and health monitoring of Bridges, mines, tunnels, DAMS, buildings, etc. By measuring the strain distribution of the structure, the local load and health of the structure can be predicted. Fiber Bragg grating sensors can be attached to the surface of the structure or pre-bought structure, and carry out health monitoring, impact detection, shape control and vibration damping detection on the structure at the same time to monitor the defects of the structure.
