Abstract

L'invention concerne un document d'identification stratifié multicouche comprenant une couche externe ayant une image de surface profilée formée à l'intérieur de ladite couche externe par ablation laser. L'image de surface profilée possède des contours basés sur une image numérique monochrome et est d'un premier aspect lorsqu'elle est observée par une lumière réfléchie à un premier angle et est d'un second aspect différent lorsqu'elle est observée par la lumière réfléchie à un second angle, différent du premier. Le document d'identification stratifié multicouche est formé par génération d'une seconde image numérique monochrome avec des motifs de pixels continus à partir d'une première image numérique monochrome et par exposition de la surface du document d'identification à un laser à l'aide de la seconde image numérique monochrome comme guide pour former une image de surface profilée sur la surface du document d'identification.
