Abstract

L'invention concerne le traitement holographique des ondes. Elle se rapporte à un procédé qui comprend la création d'un hologramme non enregistré correspondant à la modulation d'une onde de référence par une onde d'un objet particulier, cet hologramme non enregistré étant sous forme de l'image d'un hologramme enregistré qui satisfait à des critères technologiques d'un système optique utilisé et qui correspond à la modulation d'une onde virtuelle transformée de référence par l'onde objet transformée, le procédé comprenant la transformation de l'hologramme réel par un système optique et une onde de reconstitution avec création d'un hologramme non enregistré et de l'objet réel. Application aux opérations de compression de données numériques et de réduction de largeur de bande.
