Method and device for producing colored individualized holograms

A device for producing a colored individualized hologram, comprising:

• a light source providing light having a plurality of different colors (wavelengths);
• a holographic master;
• an individualization unit for spatially modulating the light individually in a color-separated manner into modulated light, the modulated light is optically guided such that the light is at least one of partly diffracted and reflected at said holographic master and is superimposed with at least one of modulated non-diffracted and reflected light in one holographic recording material such that an interference pattern representing a multicolored individualized hologram forms and the multicolored individualized hologram is stored, said individualization unit contains a plurality of spatial light modulators, and each of the plurality of colors of the light is assigned a dedicated one of said spatial light modulators, said individualization unit further having a feeding and combining optical unit, said feeding and combining optical unit configured for directing single-colored light beams onto said spatial light modulators each assigned to respective colors, said spatial light modulators individually modulate corresponding ones of the single-colored light beams simultaneously in accordance with corresponding color pixel patterns, and for collinearly combining single-colored modulated light beams to form an exposure light beam, and said spatial light modulators are oriented with respect to one another and driven such that beam combining is performed such that each of the pixels of the individualized hologram is assigned exactly one of the plurality of colors;
• an optical system;
• and
• a translation unit for moving said optical system linearly in one direction for effecting scanning of all said spatial light modulators simultaneously by the corresponding single-colored light beams.
