“Holographic near-eye displays present true three-dimensional images with full
monocular depth cues. In this paper, we propose a technique to expand the eyebox of the
holographic near-eye displays. The base eyebox of the holographic near-eye displays is determined
by the space bandwidth product of a spatial light modulator. The proposed technique replicates
and stitches the base eyebox by the combined use of a holographic optical element and high order
diffractions of the spatial light modulator, achieving horizontally and vertically expanded eyebox.
An angular spectrum wrapping technique is also applied to alleviate image distortions observed
at the boundaries between the replicated base eyeboxes.”
