METHOD OF RECORDING IRIDESCENT HOLOGRAMS Russian patent published in 1995 - IPC

Abstract RU 2040031 C1

FIELD: advertising. SUBSTANCE: holograms are recorded during two steps. At the second step of the process reference wave field which id directed onto the ancillary hologram, is formed with specific radius of curvature. he radius is related with distance between the object and the medium to be registered for recording ancillary hologram and distance between the observer and iridescent hologram by a specific relation. As a result, angle of view of the image recovered from the iridescent hologram may be increased. EFFECT: improved efficiency. 1 dwg
