ABSTRACT:
A hologram is formed of an object by calculating a two dimensional complex field distribution for a diffraction pattern of the object, and then modulating a first coherent light beam with amplitude and phase values of the two-dimensional complex field distribution as the first coherent light beam is scanned across a recording medium. A second reference coherent light beam is scanned across the recording medium and intersects the first modulated coherent light beam in the recording medium as the two beams are scanned. A reflection hologram is synthesized in the recording medium by directing the two beams from opposite sides of the film recording medium.
