Abstract
La présente invention concerne un dispositif de génération d’image (4) comprenant une source de lumière (11) produisant un faisceau lumineux (L), et un écran (12) traversé par le faisceau lumineux (L) et conçu pour modifier le faisceau lumineux (L) de manière à former une image, lequel dispositif de génération d’image (4) comprend encore un élément partiellement transparent (22) traversé par le faisceau lumineux (L) et agencé pour limiter l’échauffement dudit écran (12), caractérisé en ce que ledit élément partiellement transparent (22) est placé en aval dudit écran (12) par rapport à la source de lumière (11). De manière avantageuse un polariseur additionnel peut être placé en aval dudit élément partiellement transparent (22).Figure pour l’abrégé : Fig. 1
