Abstract
A near-to-eye display device includes a spatial light modulator. The spatial light modulator modulates an illumination wave to create a virtual-scene wave that is steered to a useful portion of an exit pupil plane. Higher diffraction orders and noise beams are filtered out by the user's pupil acting as a spatial filter.
