FOCUSING AND SCANNING OF BULK ACOUSTIC WAVE IN SOLID
-
Abstract
The focusing and scanning of the acoustic beam in solid have been carried out by using the Fresnel transducer array of ZnO thin film with a bandwidth of 200MHz. Some useful properties were observed experimentally by the acousto-optic method and analysed phenomenologically.
