Eyebox expansion and vision correction for varifocal near-eye-display

We present a varifocal near-eye-display with large eyebox and vision correction capability. The proposed scheme uses a dihedral corner reflector array (DCRA) and a varifocal lens. The DCRA forms a real image of the varifocal lens onto the eye pupil plane, creating larger eyebox than the conventional system at the same varifocal lens aperture size. The vision correcting optics can be placed at the side of the eye, clearing the space between the eye and the optical combiner. Detailed system configuration and the experimental results will be introduced in the presentation.
