  • acoustical holography

The optical reconstruction of image information contained in a sound field. First the diffraction pattern, formed by an object irradiated by ultrasonic rays, interferes with a mutually coherent reference wave. The consequent spatial irradiance distribution is then recorded. The acoustical hologram is illuminated by a light beam, resulting in diffraction from the hologram that can be used to form a three-dimensional visual image of the object.
