Abstract
A method of and apparatus for imaging objects utilizing acoustic waves wherein an acoustic beam or beams are generated at one or more frequencies and are focused into proximity with the object to generate output acoustic energy at a different frequency or frequencies resultant from nonlinear interactions with the resultant production, after detection and conversion to electric output signals, of high resolution, enhanced images.
