Abstract
L'invention concerne un appareil et des procédés permettant de générer une image par holographie, ainsi que des modulateurs de lumière spatiaux que l'on utilise dans ces techniques. L'invention concerne tout particulièrement un modulateur de lumière spatial (SLM) comprenant plusieurs pixels de modulation de lumière afin de diffracter un faisceau de lumière cohérente et de générer ainsi une image à partir d'un hologramme affiché sur ledit SLM, l'un au moins des pixels de modulation de lumière étant remplacé par un pixel de détection de lumière afin de détecter une intensité dudit faisceau de lumière cohérente à la position du pixel de détection de lumière. Le SLM peut être inclus dans un assemblage optique pour un système de projection d'image holographique, ceci en combinaison avec un système d'éclairage laser afin d'éclairer le SLM et un système de sortie optique afin d'émettre une image.
