Title (EN) THREE DIMENSIONAL TELEVISION SYSTEM
(FR) SYSTEME DE TELEVISION TRIDIMENSIONNEL
Abstract: front page image
(EN)A method and apparatus for producing a three-dimensional picture suitable for use with television systems. A set of representations of differing cross-sections of a scene is displayed on one or more display screens (19, 20, 21, 22). These displayed representations are optically stacked along a common optical axis by an arrangement of beam splitters (26) to form a composite three-dimensional picture. At least one positive lens (92) is included within the apparatus for repositioning the composite picture forward toward a viewing audience. A method and apparatus are also disclosed for enlarging the picture (80, 81), minimizing translucency therein and developing multiple viewing locations (100, 101) for increasing audience enjoyment.
