Paper Abstract

Due to the wavelength difference between the insonifying object wave and the reconstructing light wave ultrasonic holography as a three-dimensional imaging technique has little if any practical value. By introducing the concept of " empty US hologram" and " complete US hologram" and combining it with moire technique attempts are made to extract nonpicture-type information from US holograms. 1 .
