Advanced fiber-grating strain sensor systems for bridges, structures, and highways

Fiber Bragg grating sensor systems have wide application in the area of civil structures. The advantages of fiber grating strain sensors over electrical strain gauges such as greatly reduced size, EMI resistance, and higher temperature capability make them ideal choices for smart structure applications. Some of these fiber grating sensor systems can measure or detect multiaxis strain, transverse strain, temperature, bridge scouring, ice, and traffic flow.
