Abstract
(EN)
A product, method and apparatus are provided for making a stereoscopic hologram from a series of two-dimensional views of an object (52). The two-dimensional views are obtained from, for example, computer analysis of scans taken by medical diagnostic equipment. The views are reproduced on an LCD screen (56), and the screen then serves as the modulator of the holographic object beam (60). An exposure of each view is sequentially made on a different section (32K) of a holographic recording medium (28), which may be, for example, a photopolymer placed on a substrate. As the observer views the finished product, each eye looks at a different section of the hologram, thus providing a stereoscopic effect.
(FR)
L'invention se rapporte à un produit, un procédé et un appareil permettant de créer un hologramme stéréoscopique à partir d'une série de vues bidimensionnelles d'un objet (52). Les vues bidimensionnelles sont obtenues à partir, par exemple, d'une analyse informatique de balayages effectuée par un équipement de diagnostic médical. Les vues sont reproduites sur un écran à cristaux liquides (56), l'écran servant ensuite de modulateur du faisceau objet holographique (60). Chaque vue est séquentiellement reproduite sur une partie différente (32K) d'un support d'enregistrement holographique (28), qui peut être, par exemple, un photopolymère placé sur un substrat. Lorsque l'observateur observe le produit fini, chaque ÷il regarde une partie différente de l'hologramme, ce qui produit un effet stéréoscopique.
