Abstract
(EN)
Image information necessary to display a three-dimensional image of an object in a space is acquired with a simple structure, and a three-dimensional dynamic image in a true sense is displayed with a simple structure. Part of light from an object (10) falls on a polarizer (11). The polarizer (11) passes the component of the incident light polarized at a predetermined angle to the surface of the polarizer (11) and allows the component to emerge from the polarizer (11) as parallel light perpendicular to the surface of the polarizer (11). The parallel light passes through a condenser lens (12), a pinhole member (13), and a condenser lens (14) and falls on a CCD (15). The angle of incident light selected by the polarizer (11) can be changed with time. Therefore, the image information outputted from the CCD (15) is a set of items of two-dimensional image information including the direction of imaging changing with time and is necessary to display a three-dimensional image of an object in a space.

Pour afficher une image tridimensionnelle dynamique au sens réel du terme et de structure simple, on acquiert des informations d'image nécessaires à l'affichage d'une image tridimensionnelle d'un objet de structure simple dans un espace. Une partie de la lumière émanant d'un objet (10) tombe sur un polariseur (11). Ledit polariseur (11) fait passer la composante de la lumière incidente polarisée selon un angle prédéterminé vers la surface du polariseur (11), et permet à cette composante de sortir du polariseur (11) sous la forme d'un faisceau lumineux parallèle perpendiculaire à la surface du polariseur (11). Ce faisceau lumineux parallèle traverse un condenseur (12), un élément (13) à trou d'épingle, et un condenseur (14), avant de tomber sur un CCD (15). L'angle de la lumière incidente choisi par le polariseur (11) peut être modifié en fonction du temps. Par conséquent, les informations d'image émises en sortie par le CCD (15) constituent un ensemble d'informations relatives à une image bidimensionnelle comprenant la direction du changement de l'image dans le temps, lesquelles informations sont nécessaires à l'affichage d'une image tridimensionnelle d'un objet dans un espace.
