Abstract
Un dispositif d’affichage tête haute comprend une première unité de génération d’image (1) conçue pour émettre un premier faisceau lumineux amont polarisé (11), une deuxième unité de génération d’image (2) conçue pour émettre un deuxième faisceau lumineux amont polarisé (22), une lame recombinante (3) configurée pour générer en sortie un faisceau lumineux combiné (44), le faisceau combiné (44) comprenant une première composante et une deuxième composante, la première composante ayant une première direction de polarisation et la deuxième composante ayant une deuxième direction de polarisation orthogonale à la première direction de polarisation, et un système de projection (4) destiné à projeter le faisceau lumineux combiné (44) en direction d’une lame partiellement transparente (5). Ladite première direction de polarisation est inclinée par rapport au plan d’incidence (P) du faisceau lumineux combiné sur la lame partiellement transparente (5) et ladite deuxième direction de polarisation est inclinée par rapport audit plan d’incidence (P). Figure pour l’abrégé : Fig. 1A head-up display device comprises a first image generation unit (1) adapted to emit a first upstream polarized light beam (11), a second image generation unit (2) adapted to emit a second polarized upstream (22), a recombinant plate (3) configured to output a combined light beam (44), the combined beam (44) comprising a first component and a second component, the first component having a first direction of polarization and the second component having a second direction of polarization orthogonal to the first direction of polarization, and a projection system (4) intended to project the combined light beam (44) in the direction of a partially transparent plate (5). Said first direction of polarization is inclined with respect to the plane of incidence (P) of the combined light beam on the partially transparent plate (5) and said second direction of polarization is inclined with respect to said plane of incidence (P). Figure for abstract: Fig. 1
