Large scale structural monitoring is one of the most active applications of fiber Bragg grating sensors, and the measurement of mechanical parameters is crucial for the maintenance and health monitoring of bridges, mines, tunnels, dams, buildings, and other structures. By measuring the strain distribution of the above structure, the local load and health status of the structure can be predicted. Fiber Bragg grating sensors can be attached to the surface of the structure or pre purchased into the structure to simultaneously monitor its health, impact detection, shape control, and vibration damping, in order to monitor the defect situation of the structure.
