Abstract
L'invention concerne un combinateur 40 qui est utilisé pour un affichage tête haute 20 et reçoit une lumière d'image projetée sur celui-ci. Le combinateur 40 comprend : un premier substrat 51 qui comprend une première surface 41 servant de surface d'incidence pour la lumière d'image ; un second substrat 52 qui comprend une seconde surface 42 ; une couche de liaison 45 qui lie le premier substrat 51 et le second substrat 52 ; et un élément holographique 60 situé entre le premier substrat 51 et le second substrat 52. L'élément holographique 60 diffracte la lumière d'image : dans une direction de réflexion positive par rapport à la direction d'incidence de la lumière d'image sur le combinateur 40 ; ou dans une direction inclinée selon un angle de 5° ou moins par rapport à la direction de réflexion positive. Une distance LX entre l'élément holographique 60 et une position d'affichage PX d'une image imaginaire 80 qui est provoquée par la lumière d'image diffractée par l'élément holographique 60 est au moins quatre fois supérieure à une distance LY entre l'élément holographique 60 et une position d'affichage PY d'une image fantôme 81 qui est provoquée par la lumière d'image réfléchie par la première surface 41 ou la seconde surface 42.
