The invention relates to a projection device and a method for holographic reconstruction of scenes comprising a light modulator (8), an imaging system (3) with at least two imaging means (4, 5, 9) and an illumination device (1) with sufficient coherent light for illumination of a hologram (2) coded in the light modulator (8). The at least two imaging means (4,5) are relatively arranged such that a first imaging means (4) is provided for the magnified imaging of the light modulator (8) on a second imaging means (5). The second imaging means (5) is provided for imaging of a plane (10) of a spatial frequency spectrum of the light modulator (8) in a viewing plane (6) comprising at least one viewing window (15). The viewing window (6) corresponds to a diffraction order of the spatial frequency spectrum.

L'invention concerne un dispositif de projection et un procédé de reconstruction holographique de scènes. Le dispositif selon l'invention comprend un modulateur de lumière (8), un système de reproduction (3) pourvu d'au moins deux moyens de reproduction (4, 5, 9) et un dispositif d'éclairage (1) présentant une lumière suffisamment cohérente pour éclairer un hologramme (2) codé dans le modulateur de lumière (8). Les moyens de reproduction (4, 5) sont disposés l'un par rapport à l'autre de telle sorte qu'un premier moyen de reproduction (4) fournisse une reproduction agrandie du modulateur de lumière (8) sur un deuxième moyen de reproduction (5). Le deuxième moyen de reproduction (5) sert à reproduire un plan (10) d'un spectre de fréquences spatiales du modulateur de lumière (8) dans un plan d'observation (6) présentant au moins une fenêtre d'observation (15). Ladite fenêtre d'observation (6) correspond à un ordre de diffraction du spectre de fréquences spatiales.
