ABSTRACT:
A method for receiving a return signal from each of plurality M of different beam directions in media excited by a single excitation event, is to: assign each of the M directions to be substantially equally separated, by a small angular displacement from a central beam; excite the media with a single energy beam transmitted to be focused at the central beam; receive a return signal from the central beam; and for each of the M different beam directions, independently rotating the phase of the received return signal by an amount predetermined to displace the apparent focus of the response beam to the associated direction.
