Paper Abstract

Bragg gratings have been exposed into the core of optical fibers at specific locations to implement distributed, discrete gages for measurement of strain and temperature. Demonstrations using these devices to monitor composite specimen curing and bending are discussed. The sensor signals are also used in a control loop to drive an actuator for active damping of the test sample.
