Abstract
Titre : Système de projection de faisceaux lumineux L’invention concerne un système lumineux comprenant une source de lumière (1) pixelisée dotée d’une pluralité d’éléments émissifs activables sélectivement et ayant chacun une forme rectangulaire avec une dimension en hauteur et une dimension en largeur, la dimension en largeur étant identique pour tous les éléments émissifs, et un dispositif optique présentant un axe optique et configuré pour projeter une image (S) de chacun des éléments émissifs, caractérisé en ce que le dispositif optique est configuré pour que les images (S) présentent une dimension en largeur croissante de manière non linéaire à mesure que l’on s’éloigne de l’axe optique. Figure pour l’abrégé : Fig.1
