Novel Fiber Optic Sensors for Monitoring Bridge Structural Integrity

This IDEA project develops an optical fiber sensor system that represents a novel integration of the moire phenomena and fiber optics to achieve a uniquely high sensitivity and robust performance in addition to its easy installation/cabling and immunity to electromagnetic interference and lightning strikes. Upon simple modification, this sensor can measure a variety of dynamic responses of a bridge, including acceleration and displacement under traffic, earthquake and other dynamic loads. The measured structural vibration data can be used to identify structural damage and evaluate remaining capacity in real time to enhance the safety of highway bridges.
