Abstract

L'invention concerne un système de projection optique (50) comprenant une source lumineuse (12), un réseau d'éléments optiques sensiblement plats (54) servant à recevoir la lumière émise par la source lumineuse (12), et un panneau d'affichage (58) servant à émettre de manière sélective la lumière provenant du réseau d'éléments optiques. Ce dernier (54) comprend un matériau de substrat à transmission optique et une pluralité de micro-éléments optiques formés sur au moins une surface du matériau de substrat. Le panneau d'affichage (58) présente une pluralité de pixels servant à émettre de manière sélective la lumière émise par le réseau d'éléments optiques (54). Les micros-éléments peuvent comprendre des microlentilles, des microprismes, des microguides d'ondes ou toute autre combinaison appropriée de ces derniers, configurés pour modifier les caractéristiques de la lumière émise par la source lumineuse afin de créer une source d'éclairage voulue.
