Abstract

Procédé d'holographie numérique comprenant : l'illumination d'un objet S, la rotation du champ d'onde de l'objet par rapport à un capteur CCD holographique numérique de telle manière que le champ d'onde de l'objet soit déplacé à travers la surface d'enregistrement du capteur et, l'enregistrement d'une pluralité d'hologrammes (« hologrammes d'entrée ») à des positions angulaires correspondantes du champ d'onde de l'objet. Les hologrammes d'entrée sont combinés pour créer un hologramme de sortie de résolution plus haute que celle de n'importe quel hologramme d'entrée. On peut faire tourner le champ d'onde de l'objet en faisant tourner l'objet (dans le cas d'un objet 2D) ou en faisant tourner un miroir intercalé entre l'objet et le capteur (dans le cas d'un objet 3D).
