Abstract
L'invention concerne un procédé de production d'un hologramme (1), notamment d'un hologramme (1) pour des éléments de sécurité (1 a) et/ou des documents de sécurité (1 b). Un ou plusieurs plans d'hologramme virtuels (10) sont disposés devant et/ou derrière un ou plusieurs modèles virtuels (20) et/ou un ou plusieurs plans d'hologramme virtuels (10) sont disposés de telle sorte qu'ils coupent un ou plusieurs modèles virtuels (20). Une ou plusieurs sources de lumière virtuelles (30) sont disposées sur un ou plusieurs champs partiels de la surface (21) d'un ou plusieurs des modèles virtuels (20). Un ou plusieurs champs électromagnétiques virtuels (40) émanant d'au moins l'une des sources de lumière virtuelles (30) sont calculés dans une ou plusieurs zones (11) de l'un ou des plusieurs plans d'hologramme virtuels (10). Un champ électromagnétique total virtuel (41) 31082021est respectivement calculé dans l'une ou les plusieurs zones (11) en se basant sur la somme d'au moins deux, notamment de tous les champs électromagnétiques virtuels (40) dans la zone (11) correspondante. Une ou plusieurs images de phase (50) sont calculées à partir des champs électromagnétiques totaux virtuels (41) 31082021dans l'une ou les plusieurs zones (11). Un profil de hauteur (sa) de l'hologramme (1) est calculé à partir de l'une ou des plusieurs images de phase (50) et le profil de hauteur (sa) de l'hologramme (1) est incorporé dans un substrat (2) en vue de fournir l'hologramme (1).
