Abstract
A bridge monitoring system uses laser light reflected from structural members of a bridge to create velocity and displacement time signals of the bridge's vibratory response to quiescent conditions, and converts the sensed velocity and displacement time data to frequency domain data to provide a “signature” waveform for the bridge indicative of its structural characteristics.
