Abstract

Dans un procédé de préparation d'une photographie d'un sujet en trois dimensions, par exemple un portrait tridimensionnel, le sujet (10) est illuminé à travers un écran de diffusion par une source de lumière laser. On place un écran (14) rétro-réfléchissant, comprenant un réseau de réflecteurs en coin de cube, devant l'écran puis on dispose une plaque (12) de fractionnement de faisceau entre ledit écran rétro-réfléchissant et le sujet, ladite plaque de fractionnement du faisceau étant inclinée par rapport au sujet de manière à réfléchir une partie de la lumière provenant de l'écran rétro-réfléchissant sur un film ou une plaque photographique (18) disposé d'un côté du sujet, de manière que la lumière laser réfléchie à partir du sujet passe par ladite plaque de fractionnement du faisceau jusqu'à l'écran rétro-réfléchissant, est réfléchie sur elle-même à la plaque de fractionnment de faisceau, et est partiellement réfléchie pour ainsi former une image réelle (16) du sujet, dans ladite lumière laser, sur le côté opposé de la plaque de fractionnement du faisceau à partir du sujet. Le film ou la plaque photographique est placé de manière à recevoir les rayons lumineux passant à travers l'image réelle et formant celle-ci, et est illuminé davantage par ladite source de lumière laser, ce qui permet de former sur ledit film ou ladite plaque, après développement classique, une image holographique tridimensionnelle que l'on peut visionner à la lumière blanche.
