Holographic near-eye displays are a promising technology to solve long-standing
challenges in virtual and augmented reality display systems. Over the last few years, many …

The evolution of computer-generated holography (CGH) algorithms has prompted significant
improvements in the performances of holographic displays. Nonetheless, they start to …

In this paper, we present a novel method the étendue expansion of near-eye holographic
displays through the generation of a sparse eye-box. Conventional holographic near-eye …

Joint photographic experts group (JPEG) compression standard is widely adopted for digital
images. However, as JPEG encoding is not designed for holograms, applying it typically …

Holographic near-eye display is thought as one of ideal entrance of “metaverse”, since it
reconstructs the full wavefront information and provides all kinds of depth cues for human …

Holographic display faces the trade-off between image quality and focus cues, resulting from
the specific choice of phase distribution. In this Letter, we propose a speckle-free …

The Visual Turing Test is the ultimate goal to evaluate the realism of holographic displays.
Previous studies have focused on addressing challenges such as limited étendue and …

Spatial light modulator (SLM) technology forms the centerpiece of digital holographic
displays. However, an inherent limitation of these devices is that their etendue, defined as …

A multiple sub-holograms optimization method for holographic near-eye display (NED)
based on holographic viewing-window (HVW) is proposed. The HVW is a hologram …

In holographic near-eye display, the limited aperture of the eye pupil results in the partial
and incomplete sampling of the diffracted light wavefront. It will influence the quality of the …
