CA 2284915

An autostereo projection system uses multiple projectors to form an essentially seamless and extended field of view. Each projector is registered to a CRT display. Shutter elements in each projector create multiple pupils for each CRT display. Each CRT display is driven with different images for each shutter pupil. Seamlessness is promoted by the use of a tunable optical diffuser as part of a common lenticular viewing lens.

L'invention porte sur un système de projection autostéréoscopique qui met en oeuvre plusieurs projecteurs de façon à obtenir un champ de vision essentiellement continu et étendu. On fait correspondre chaque projecteur avec un afficheur à tube cathodique. Les éléments d'obturation de chaque projecteur forment une pluralité de diaphragmes pour chaque afficheur à tube cathodique. Chacun de ces afficheurs fonctionne de façon à donner des images différentes à raison d'une pour chaque diaphragme d'obturateur. La continuité est favorisée par l'utilisation d'un diffuseur optique accordable faisant partie d'une lentille de visualisation lenticulaire ordinaire.
