Abstract

Le système décrit ci-dessous permet de reproduire des informations holographiques multiplexées à partir d'un support original (100, 300, 400, 500, 600, 720) sur un support de reproduction (200, 310, 410, 510, 610, 730). Il lit simultanément les informations venant de tous les hologrammes originaux contenus dans le même support original et les enregistre sur le support de reproduction. La copie présente des distributions de phase et d'amplitude différentes du support original contenant une pluralité d'hologrammes multiplexés (420, 520), bien que la copie et l'original contiennent des informations holographiques identiques des objets originaux.
