Abstract

Un procédé et un appareil pour améliorer l'aspect des visualisations holographiques reproduites à partir d'hologrammes en image sont décrits. Ledit procédé et ledit appareil comprennent un filtre de réflexion holograpique (2) à travers lequel est filtrée la lumière éclairant l'hologramme. Ledit filtre est doté d'une pluralité de bandes passantes étroites, chaque bande étant associée à la fréquence de la couleur ou des couleurs devant être reproduites par l'hologramme en image (3). Un procédé pour la fabrication du filtre de réflexion de l'hologramme est également divulgué.
