摘要:
Laser techniques for ultrasonic generation and reception have potential for a wide range of non-contact measurements, chiefly because they can be used for defect detection and materials characterisation at elevated temperatures. However, these techniques have other advantages. Unlike contact transducers, they do not disturb elastic wave propagation by loading the surface of the specimen. They are also capable of much higher temporal and spatial resolution than can be obtained by most conventional techniques.
