Abstract
A pulsed laser has been used to generate ultrasonic transients in samp les of metal and fiber-reinforced polymer composite material. These ha ve been detected using an air-coupled piezoelectric transducer. It is demonstrated that such a transduction system can be used for longitudi nal waves in bulk material, Rayleigh waves at solid surfaces and Lamb waves in thin plates.
