Abstract (en)
[origin: WO2019048499A1] The invention relates to a method for producing a hologram (1), in particular a hologram (1) for security elements (1a) and/or security documents (1b). One or more virtual hologram planes (10) are arranged in front of and/or behind one or more virtual models (20) and/or one or more virtual hologram planes (10) are arranged such that they intersect one or more virtual models (20). One or more virtual light sources (30) are arranged on one or more portions of the surface (21) of one or more of the virtual models (20). One or more virtual electromagnetic fields (40) are calculated starting from at least one of the virtual light sources (30) in one or more zones (11) of the one or more virtual hologram planes (10). A virtual total electromagnetic field (41) is calculated in each of the one or more zones (11) on the basis of the sum of two or more, in particular of all of the virtual electromagnetic fields (40) in each zone (11). One or more phase images (50) are calculated from the virtual total electromagnetic fields (41) in the one or more zones (11). An elevation profile (60) of the hologram (1) is calculated from the one or more phase images (50) and the elevation profile (60) of the hologram (1) is incorporated into a substrate (2) in order to provide the hologram (1).
