Abstract

Hologrammes hybrides visibles par lumière blanche et leurs procédés de fabrication. L'invention concerne des hologrammes hybrides par réflexion fabriqués en utilisant des structures diffractives ou des réseaux d'un objet holographique comme un hologramme par transmission ou un élément optique holographique (HOE). Les fronts d'onde des structures diffractives sont convertis en un hologramme par réflexion en les balayant avec une source de lumière cohérente ayant un faisceau étroit. L'hologramme hybride par réflexion peut avoir des paramètres d'affichage comme les couleurs multiples, la solidité, et la stabilité de couleur des hologrammes par réflexion de lumière blanche, le changement diffractif de couleur d'un hologramme par transmission de lumière blanche, l'imagerie à trois dimensions et une grande variété de changements dynamiques. On peut combiner dans un seul hologramme, différentes régions ou images présentant chacun de ces effets. Ces hologrammes hybrides par réflexion sont idéals pour les applications liées à la sécurité ou à la prévention de la contrefaçon.
