Investigation of the laser ultrasound propagation in K9 glass using optical interferometry
文献摘要：
The propagating of laser-generated ultrasonic waves in K9 glass was investigated.Many methods have been developed to detect the laser ultrasound since laser ultrasonic waves can be used to measure material parameters or characterize materials properties.In order to reduce the measuring time,a Mach-Zehnder interferometer,a full field measuring tool,was preferred in this paper.The ultrasonic wave was produced on the K9 glass surface by a Q-switched Nd∶YAG laser absorbed in a liquid layer.The interferograms were then taken at various delay times by a CCD camera after single pulse induced laser ultrasonic waves.Ultrasonic waves in the K9 glass can be observed from interferogram images.The results provide an understanding of laser ultrasound propagation in K9 glass in the lifetime.
