Abstract

This paper describes a non-destructive inspection technique based on the interaction of ultrasonic S_O 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.
