Abstract

Agencement et procédé de projection en relief, de préférence pour des images animées formant une série d'images de gauche et d'images de droite alternées. Cet agencement de projection est pourvu d'une fenêtre (L1) située dans le trajet des rayons lumineux dudit agencement, de sorte qu'une torsion soit appliquée à la lumière polarisée lorsqu'on alterne entre image de gauche et image de droite.
