ABSTRACT:
A method and apparatus for three dimensional imaging of a solid angular volume utilizing a single pulse of radiated energy is described. An embodiment is disclosed which utilizes a single unipolar acoustic pulse to insonify a three dimensional volume. An array of transducers is used to collect the echoes which are stored in a memory as a replica of the reflected three dimensional wavefield. This data is processed to form a replica of the three dimensional volume of objects responsible for the echoes which is then stored in a second three dimensional memory. The data in this memory is collapsed in the direction of preferred perspective to enable viewing on a cathode ray tube.
