Abstract

L'invention concerne un afficheur (1) tête haute comprenant : - un écran (11) duquel émerge un faisceau de rayons lumineux présentant un rayon principal (RP), et - un système optique de projection comportant au moins un miroir (12) et adapté pour projeter le faisceau de rayons lumineux vers une lame (2) partiellement transparente afin de former, par réflexion par ladite lame, une image virtuelle (IMV) de l'écran, ledit miroir étant monté mobile en rotation entre une première et une deuxième position. Selon l'invention, l'afficheur comporte en outre des moyens de réglage pour modifier la position et/ou l'orientation présentées par ledit rayon principal en sortie de l'unité de génération d'image, par rapport audit miroir, de manière que, après réflexion par ledit miroir et par ladite lame, ledit rayon principal passe par une même position fixe, pour la première ainsi que pour la deuxième position dudit miroir.The invention relates to a head-up display (1) comprising: - a screen (11) from which emerges a beam of light rays having a main ray (RP), and - a projection optical system comprising at least one mirror (12) and adapted to project the beam of light rays towards a partially transparent plate (2) in order to form, by reflection by said plate, a virtual image (VMI) of the screen, said mirror being mounted to be movable in rotation between a first and a second position. According to the invention, the display further comprises adjustment means for modifying the position and / or the orientation presented by said main beam at the output of the image generation unit, relative to said mirror, so that , after reflection by said mirror and by said plate, said main ray passes through the same fixed position, for the first as well as for the second position of said mirror.
