Abstract: A projection device is provided for displaying at least one of a two-dimensional and three-dimensional scene or of content. The projection device comprises an illumination device, at least two spatial light modulator devices and an optical system. The illumination device comprises at least one light source for generating a holographic illumination. One of said spatial light modulator devices is designed as spatial light modulator device modulating at least the phase of the light for the holographical generation of illumination patterns. This spatial light modulator device as first spatial light modulator device is followed by a second spatial light modulator device. The optical system is disposed to illuminate the second spatial light modulator device with a predefinable light distribution generated by the first spatial light modulator device.

Abstract: Spatial light modulator configured as a periodic structure of polymer grating layers arranged essentially at equal distances and intermediate spaces to form a periodic grating structure. The surfaces bounding the periodic grating structure have electrodes influencing the refractive index of the active optical medium by an electric field. The electrodes have a pixelated arrangement and can be driven independently of each other with an electrical voltage. The orientation layer thickness and grating period of the periodic grating structure are configured so that they do not correspond to the Bragg condition for the light from at least one light source, and so that for light from the at least one light source incident on the spatial light modulator the light fraction deviated owing to Bragg diffraction is less than the undeviated transmitted light fraction.
