Patent ID: 8736933

Claim:
A method for producing a colored individualized hologram, which comprises the steps of: generating light having a plurality of different colors (wavelengths); spatially modulating the light individually in a color-separated manner resulting in modulated light, the light is modulated simultaneously in the color-separated manner by means of a plurality of spatial light modulators, each of the plurality of different colors of the light is assigned a dedicated one of said spatial light modulators that individually modulates a single-colored light beam and having a corresponding color resulting in a plurality of single-colored modulated light beams having the plurality of colors; effecting a translational linear movement of an optical system to achieve simultaneous scanning beam guidance of single-colored light beams across a corresponding one of the spatial light modulators; combining collinearly the plurality of single-colored modulated light beams having the plurality of colors to form a multicolored exposure light beam modulated individually in a color-separated manner, the spatial light modulators being disposed with respect to one another in such a way, and the combining is performed such that each pixel of an individualized hologram is assigned exactly one of the plurality of colors; optically guiding the modulated light such that the light is at least one of partly diffracted and reflected at a holographic master and is superimposed with at least one of modulated non-diffracted light and reflected light in one holographic recording material such that an interference pattern representing the multicolored individualized hologram will form; and storing the multicolored individualized hologram.
