Abstract

This study presents a damage detection system using modulated ultrasonic and fiber Bragg grating (FBG) in Aluminum thin plate. In the system, modulated ultrasonic technology and FBG sensing technology were combined to detect damage. Piezoelectric patches used to excite ultrasonic and FBG were pasted on a Acrylic plate and then contacted with specimen by coupling, so the excitation point of ultrasonic and sensing point of FBG can be modified arbitrarily. Experiment results showed that the system can detect the damage signal more flexibly.
