用脉冲激光在金属和纤维增强聚合物复合材料样品中产生超声瞬态。这些已被检测到使用空气耦合压电换能器。结果表明，这种换能系统可用于体材料中的纵波、固体表面的瑞利波和薄板中的兰姆波。&lt;<ETX>&gt;
A pulsed laser has been used to generate ultrasonic transients in samples of metal and fiber-reinforced polymer composite material. These have been detected using an air-coupled piezoelectric transducer. It is demonstrated that such a transduction system can be used for longitudinal waves in bulk material, Rayleigh waves at solid surfaces and Lamb waves in thin plates.<<ETX>>
