Abstract

L'invention concerne un afficheur tête-haute (10) pour un véhicule automobile (3), comportant une première unité de génération d'images (11) comprenant un premier scanner laser (13, 14, 15) ayant une diode laser émettant à une première longueur d'onde (λ1), cette première unité étant commandée par un calculateur (30) pour générer des premières images (Img1) ; une deuxième unité de génération d'images (12) commandée par le calculateur pour générer des deuxièmes images (Img2), cette deuxième unité étant adaptée à générer un faisceau lumineux dans une bande de longueurs d'onde (Δλ) comprenant une deuxième longueur d'onde (λ4) ; et un ensemble optique (18) de projection d'images, adapté à projeter les premières et deuxièmes images dans le champ de vision d'un conducteur (2) et comportant un filtre optique (19) spectralement sélectif adapté à réfléchir la lumière à la première longueur d'onde et à transmettre la lumière dans une majeure partie de la bande de longueurs d'onde. Selon l'invention, les première et deuxième unités sont placées de part et d'autre du filtre optique de sorte que les premières et deuxièmes images sont formées respectivement dans un premier plan-image (P1) et dans un deuxième plan-image (P2), et le calculateur commandant la première unité est configuré pour traiter un ensemble de données relatives à l'environnement faisant face au véhicule de manière à superposer une première image avec au moins un objet particulier de cet environnement.The invention relates to a head-up display (10) for a motor vehicle (3), comprising a first image generation unit (11) comprising a first laser scanner (13, 14, 15) having a laser diode emitting at a first wavelength (λ1), this first unit being controlled by a computer (30) to generate first images (Img1); a second image generation unit (12) controlled by the computer to generate second images (Img2), this second unit being adapted to generate a light beam in a band of wavelengths (Δλ) comprising a second length d 'wave (λ4); and an optical image projection assembly (18), adapted to project the first and second images in the field of view of a conductor (2) and comprising a spectrally selective optical filter (19) adapted to reflect light at the first wavelength and to transmit light in a major part of the wavelength band. According to the invention, the first and second units are placed on either side of the optical filter so that the first and second images are formed respectively in a first image plane (P1) and in a second image plane (P2 ), and the computer controlling the first unit is configured to process a set of data relating to the environment facing the vehicle so as to superimpose a first image with at least one particular object of this environment.
