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 matériel (12) conçu pour modifier le faisceau lumineux (L) de manière à former une image. Le 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 matériel (12). Le dispositif de génération d’image (4) comprend un filtre infra rouge (21) disposé en aval dudit matériel (12) par rapport à la source de lumière (11).Figure pour l’abrégé : Fig. 1
