摘要
Abstract
Ultrasonic technology has been widely used in the manufacture industry.However,there are few published reports about real-time monitoring of the ultrasonic vibration.An experimental method was presented to track and measure the ultrasonic vibration in this paper.A state-of-art ultra high-speed/high-accuracy charge-coupled device (CCD)laser displacement sensor is used to track and measure the ultrasonic vibration from ultrasonic generator,then a series of Matlab programs are developed to fil-ter noise from original data.The ultrasonic vibration frequency and period are evaluated and the ultra-sonic amplitude is measured within accuracy ± 0.1 μm.Effect of the ultrasonic power on the ultrasonic amplitude is also investigated.关键词
