Title (EN) HOLOGRAMS AND FABRICATION PROCESSES
(FR) HOLOGRAMMES ET PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)We describe a method of fabricating a stereoscopic hologram of an object, the method comprising: capturing a sequence of two-dimensional images of the object by replaying said captured sequence of images one at a time using coherent light to reproduce said sequence of captured images on a diffusing screen; recording a first volume hologram during said replaying of said captured sequence of images; replaying said first volume hologram to replay together said images recorded in said different spatial locations on said surface of said first volume hologram and recording a second, volume reflection hologram of said replayed stereoscopic image of said object replayed by said first volume hologram to provide said stereoscopic hologram of said object.
(FR)L'invention concerne un procédé de fabrication d'hologramme stéréoscopique d'objet, consistant : à capturer une séquence d'images bidimensionnelles de l'objet par relecture de la séquence d'images capturée une à la fois au moyen d'une lumière cohérente pour reproduire ladite séquence d'images capturées sur un écran de diffusion ; à enregistrer un premier hologramme de volume pendant la relecture de la séquence d'images capturée ; à relire le premier hologramme de volume pour relire conjointement les images enregistrées à différents emplacements spatiaux sur la surface du premier hologramme de volume, et à enregistrer un second hologramme de réflexion de volume de l'image stéréoscopique relue de l'objet relu par le premier hologramme de volume afin d'obtenir l'hologramme stéréoscopique de l'objet.
