Abstract
The invention relates to a display device, in particular a head-mounted display or hocular, having a spatial light modulator and a controllable light-deflecting device for generating a multiple image of the spatial light modulator, which consists of segments, the multiple image being produced at least with a predefinable number of segments which determines the size of a visible area within which a 3D-scene holographically encoded in the spatial light modulator can be reconstructed for observation by an eye of an observer.
Claims24
A display device, in particular a head-mounted display or hocular, comprising a spatial light modulator, a light-deflecting device and at least one optical imaging system, where
- the spatial light modulator comprising a hologram in which a scene is encoded is illuminated with wave fronts which are sufficiently coherent at least in one direction,
- a multiple image of the spatial light modulator is generated by the light-deflecting device, said multiple image being composed of segments which are sequentially joined at least in one dimension,
- the segments of the multiple image of the spatial light modulator are magnified and partly overlap, where the overlapping areas are allowed for in the encoded hologram,
- the multiple image includes at least a defined number of segments and defines the size of a volume of view in which the scene is reconstructed to be viewed by an observer eye.
