Abstract

Un combineur (10) pour afficheur tête haute comprend une première face (Φ1) destinée à recevoir un rayonnement lumineux généré par un dispositif de projection et une seconde face (Φ2) opposée à la première face (Φ1) ; Une lame quart d'onde (18) est interposée entre la première face (Φ1) et la seconde face (Φ2). Un afficheur tête haute comprenant un tel combineur et un procédé de fabrication d'un combineur sont également proposés.
