Abstract
Augmented reality glasses include near eye displays the include sources of imagewise amplitude modulated light optical coupled to spatial phase modulators or active zone plate modulators and optically coupled to eye coupling optics. The sources of imagewise amplitude modulated light can include emissive 2D display panels or light sources coupled to imagewise amplitude modulators. The eye coupling optics can include volume holographic diffraction gratings.
Claims11
A near eye display system comprising:
- a source of imagewise amplitude modulated light;
- a spatial phase modulator optically coupled to the source of imagewise amplitude modulated light, wherein the spatial phase modulator is configured to impart a wavefront curvature to light received from the source of imagewise amplitude modulated light;
- and
- eye coupling optics optically coupled to the spatial phase modulator.
