Abstract

L'invention concerne un dispositif de représentation d'images stéréoscopiques tridimensionnelles équipé d'une plaque de base porteuse d'images (1) sur laquelle sont fixés des couples d'images (K1, K2 ... Kn) composés de bandes (B1 ... Bn, J1 ... Jn) correspondant à la position de l'oeil gauche ou droit. De plus, une grille d'observation (2) est fixée sur la moitié de la plaque de base porteuse d'images (1) côté observation.
