Abstract
The invention relates to a method for the production of a multicolor hologram by means of a capture beam, wherein the utilized capture beam () has a plurality of beam bundles of the same wavelength. Advantageously, the multicolor hologram is produced by copying the structure of multiple single-color subholograms of a master hologram () in a copy layer () which is affixed parallel to the master hologram, by illuminating this copy layer with the single-color capture beam. Each beam bundle appears at a prespecified angle of incidence, wherein the angles of incidence are calculated in such a manner that the structure of a corresponding subhologram is produced in the copy layer. In this way, a falsification is nearly impossible.
