An optical system for a head mounted display includes a light pipe having two parallel surfaces along which modes can travel by total internal reflection. An illumination element allows selection of modes so that the desired modes can be transmitted along the light pipe, either axially or by total internal reflection.

L'invention concerne un système optique pour un système de projection tête haute. Ledit système comprend un conduit de lumière présentant deux surfaces parallèles le long desquelles des modes peuvent se déplacer par réflexion interne totale. Un élément d'éclairage permet la sélection de modes de sorte que les modes souhaités peuvent être transmis le long du conduit de lumière, axialement ou par réflexion interne totale.
