PRODUCTION OF COPY MASTER OF LIPPMANN FULL-COLOR HOLOGRAM AND METHOD FOR DUPLICATING THE HOLOGRAM

摘要

PURPOSE: To improve productivity by greatly simplifying operations to duplicate the Lippmann holograms. ;CONSTITUTION: Respective copy masters 10R, 10G, 10B for respective color components are produced by setting the respective incident angles of incident reference beams and object beams on respective hologram photosensitive materials 10 for respective color components in such a manner that the directions of the reconstructing beams thereof are respectively set the same, then making these beams incident on the photosensitive materials. These copy masters 10R, 10G, 10B are superposed on each other and the hologram photosensitive materials are arranged on the upper layer thereof. The reconstructing illumination beams of the same wavelength are made incident on the copy masters 10R, 10G, 10B according to the respective incident angles of the respective reference beams at the time of producing the respective copy masters in this state and the respective reconstructing beams from these copy masters are recorded on the hologram photosensitive materials, by which the holograms are duplicated.;COPYRIGHT: (C)1995,JPO
