Abstract

Un dispositif d'affichage tête haute (2) comprend : - une unité de génération d'image (4) conçue pour émettre, selon une direction de propagation (D), un faisceau lumineux amont (Fi) présentant une polarisation rectiligne orientée selon une première direction donnée (Pi) perpendiculaire à la direction de propagation (D) ; et - un système optique (6) configuré pour recevoir en entrée le faisceau lumineux amont (Fi) et pour projeter en sortie un faisceau lumineux aval (Ff) en direction d'une lame partiellement transparente (7). Le faisceau lumineux aval (Ff) présente une polarisation rectiligne orientée selon une seconde direction donnée oblique par rapport au plan d'incidence du faisceau lumineux aval (Ff) sur la lame partiellement transparente (7).
