Title (EN) BEAM-SPLITTER WITH AN ANGLED REAR SURFACE
(FR) DIVISEUR DE FAISCEAU À SURFACE ARRIÈRE INCLINÉE
Abstract:
(EN) A beam-splitter can be provided with the deleterious effects of double images removed. For example, front and rear surface of the beam-splitter's transparent substrate can be arranged in a non-parallel fashion configured to eliminate the visible appearance of a ghost image. The aspects disclosed herein may be employed with a head-up display (HUD), an augment reality (AR) HUD, or any implementation employing at least two picture generation units.
(FR) Selon la présente invention, un diviseur de faisceau peut disposer des effets délétères d'images doubles éliminées. À titre d'exemple, une surface avant et une surface arrière du substrat transparent du diviseur de faisceau peuvent être disposées de manière non parallèle et configurées pour supprimer l'aspect visible d'une image fantôme. Les aspects de l'invention peuvent être utilisés avec un affichage tête haute (HUD), un HUD à réalité augmentée (AR), ou toute mise en œuvre faisant appel à au moins deux unités de génération d'image.
