摘要：

A laser-scanning vibrometer can be used for measuring even the smallest motions of the active area of ultrasonic transducers. Additionally, a new method for measuring and visualising the acoustic sound waves, emitted from such transducers, is developed. The new method, too, is based on laser-scanning vibrometry and allows the contact-less measurement of ultrasound fields with high spatial resolution. The combination of both techniques permits to analyse and optimise the acoustic behaviour of ultrasonic transducers. Moreover, the method is qualified for investigating and presenting numerous acoustic phenomena. (C) 2003 Elsevier B.V. All rights reserved.
