Abstract
This letter describes the formation of acoustic holograms retaining the properties of holograms made by the Leith-Upatneiks method without requiring the use of an acoustic reference wave. Holograms are recorded by scanning a linear transducer over an inclined plane; the phase reference is synthesized electronically in the receiver. Experimental results in air at 25 kHz are described.Keywords
