摘要:

A simple acoustic scanning device has been devised in which a chirped SAW beam is converted into a focused scanning bulk wave beam by coherent scattering from a grating of parallel grooves. The device can operate in both transmitting and receiving modes, and is applicable to the acoustic imaging of objects in real time.
