“…See-real has developed a technology that changes the viewing window by applying a directional backlight and eye-tracking technology to a large-scale flat panel-type holographic display [Häussler et al 2009]. Similar approaches have been studied in other 3D displays, such as compressive light field or depth fused displays [Maimone et al 2014;. In near-eye displays, waveguide-type displays replicate the exit-pupils for eye-box expandsion [Levola 2006;Yu et al 2017], however, the replicated exit-pupils can only have focus distance at infinite distance intrinsically.…”

Holographic displays have great potential to realize mixed reality by modulating the wavefront of light in a fundamental manner. As a computational display, holographic displays offer a large degree of freedom, such as focus cue generation and vision correction. However, the limited bandwidth of spatial light modulator imposes an inherent trade-off relationship between the field of view and eye-box size. Thus, we demonstrate the first practical eye-box expansion method for a holographic near-eye display. Instead of providing an intrinsic large exit-pupil, we shift the optical system's exit-pupil to cover the expanded eye-box area with pupil-tracking. For compact implementation, a pupil-shifting holographic optical element (PSHOE) is proposed that can reduce the form factor for exit-pupil shifting. A thorough analysis of the design parameters and display performance are provided. In particular, we provide a comprehensive analysis of the incorporation of the holographic optical element into a holographic display system. The influence of holographic optical elements on the intrinsic exit-pupil and pupil switching is revealed by numerical simulation and Wigner distribution function analysis.

“…The multiplicative multi-panel displays on other hand consist of multiple simultaneously active layers that successively modulate the propagated light rays to synthesize the proper views. This has been demonstrated using dual-layer compressive LF display combined with face tracking [8]. Note that the quality of the multiplicative display is highly dependent on the resolution and the refresh rate of the spatial light modulator panels which is not the case for the additive ones since the panels are merely used as rear projection shutters.…”

Light fields preserve angular information which can be retargeted to multi-panel depth displays. Due to limited aperture size and constrained spatial-angular sampling of many light field capture systems, the displayed light fields provide only a narrow viewing zone in which parallax views can be supported. In addition, multi-panel displays typically have a reduced number of panels being able to coarsely sample depth content resulting in a layered appearance of light fields. We propose a light field retargeting technique for multi-panel displays that enhances the perceived parallax and achieves seamless transition over different depths and viewing angles. This is accomplished by slicing the captured light fields according to their depth content, boosting the parallax, and blending the results across the panels. Displayed views are synthesized and aligned dynamically according to the position of the viewer. The proposed technique is outlined, simulated and verified experimentally on a three-panel aerial display.

In this paper, we propose a method to extend the viewing field of a compressive light field display by optimizing the maximum viewing angle. The difference from existing work is the improvement in the overall visual effect of compressive light field display rather than only extending the viewing field region. Sliding window scanning and viewer detection are also used for determining the target region and optimizing the display. Experiments demonstrate that the proposed method provides a relatively desirable improvement for the whole visual effect of compressive light field display, especially for the performance in the non-target display region.
