Abstract

Fiber grating strain sensors offer a means to monitor the health of highways and bridges as well as a means to monitor vehicular traffic patterns and critical data such as speed, weight, and classification of vehicle types. This paper overviews recent results associated with employing very high speed demodulation systems with capabilities in excess of 10 kHz and strain sensitivities on the order of one microstrain. It is clearly shown that this type of system can be used as an effective traffic monitoring tool as well as for health monitoring purposes.
