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.
Claims13
A near-eye display device, comprising:
- a light source generating a divergent wave front;
- a spatial light modulator comprising a hologram configured to receive light from the light source and form an image;
- and
- a combiner comprising at least one holographic optical element positioned to receive light from the spatial light modulator and to redirect the light toward a viewing window, the at least one holographic optical element being positioned between the viewing window and a view of an external environment to combine a view of the image formed by the spatial light modulator and the view of the external environment.
