摘要： An acoustically generated image includes only selected acoustical components. When an original acoustic signal interacts with an object, the resultant acoustic signal comprises a diffracted component and an undiffracted component. The acoustical images of the present invention are generated with either the diffracted component only or the undiffracted component only. In an alternative embodiment, the acoustically generated image may comprise selected frequency component(s) from the diffracted component of the acoustic signal.
