Paper Abstract

This paper describes a non-destructive inspection technique based on the interaction of ultrasonic SO Lamb waves with holes, regions of impact damage, and delaminations, in carbon fiber composite plates. The Lamb waves were detected using a surface bonded, single mode optical fiber sensor operating at a wavelength of 633 nm forming one arm of an optical fiber Mach Zehnder interferometer. Lamb generation was accomplished by use of perspex coupled piezo-electric transducers.
