Abstract :
An instrument has been designed and experiments carried out to determine the resolution which may be possible using airborne ultrasonics as a sensing medium. The experiments were conducted using one transmitter and two receivers from which it is shown that a resolution of the order of a 3 mm cube is practicable using a single wide angle radiator and a surrounding cluster of 3 wide angle receptors.
