METHOD FOR HOLOGRAMS AND HOLOGRAPHIC PRINTINGS CONTACT COPYING

摘要

This invention is related to holography and is used for contact copying method of hologram and holographic printings with impulsive and permanent operation laser. Also this invention can be used for relief objects (coins, pictures) copying and for making Denisiuk type holograms of these objects. The proposed method by which unexploited light-sensitive material, applied on the base is parallel with the placed copying hologram or holographic printing is lighted by the coherent narrow gap shaped laser beam this way it's lighten unexposed light-sensitive material zone, have to be parallel to coherent light falling direction projection to copied hologram or holographic printing surface. And this zone is moved unexposed light-sensitive material and copied hologram or holographic printing surface direction. It is perpendicular to coherent light beam, and it lights copied hologram or holographic printing and recreating the view, of falling direction projection to abovementioned materials surface planes.
