Abstract

A plurality of acoustic source and / or detector elements are employed in a scanning mode to acoustically illuminate and acquire acoustic data from numerous sites within a larger target area. Based on the acoustic data collected in the scanning mode, a localised site within the target area is selected as the target site for focused acoustic illumination and / or probing. Elements of the acoustic source / detector array are focused on the selected target site in an automated fashion. Thereafter, the target area is periodically scanned and the acoustic focus repositioned, as required, to maintain the focus of the acoustic source at the desired target site.
