Paper Abstract

This paper reports a new monitoring system with the fiber- optic sensors that embedded in composite material. The system can be used for the structural health monitoring of composite material. As the etched fibers embedded in composite material are acted upon by the internal stress of the material, the light signals traveling in the fibers will decrease or vanish. The fibers are embedded in composite material perpendicularly to build a 2-D fiber optic sensor array that can determining the locations of the structural damages in the composite material. The paper discussed the photoelectric transformation by a CCD and the photoelectric signal processing. The results of the real-time monitoring are given.
