Phase profiles for holographic stereograms

Optical Engineering, 1995
The diffractive phase profile of holographic stereograms is calculated using different types of diffusing functions, which can be categorized in two groups: object-dependent and object-independent diffusers. It is shown that object-independent diffusing profiles lead to considerable computational savings at the expense of some interperspective leakage.

Three-Dimensional TV Using Holographic Stereogram

2010 IEEE/ACIS 9th International Conference on Computer and Information Science, 2010
Computer holographic stereogram (CHS) is useful for holographic 3D TV because it is constructed from the multi camera horizontal viewpoint plane images and is compatible to the multi holographic stereogram image. Each hologram is recorded as a slit hologram (element hologram) but total viewing area and the number of the element holograms have been ...

13.4: The Realism of Reflection Holographic Stereograms

SID Symposium Digest of Technical Papers, 2001
Abstract The realism of reflection holographic stereograms was evaluated to determine how acceptable they are to a non‐technical audience. The stereograms were rated for realism by comparing them to photographic images and real objects. Although the ratings were favorable, they did not quite achieve the realism of photographic images,

Holographic stereogram using graphic accelerator

SPIE Proceedings, 2006
A holographic stereogram is one of methods for displaying 3-D image data from multiple-view images. In this paper, we propose a method for computing holographic stereogram using graphic accelerator. We use graphic accelerator at two stages of method. One is creating Multiple-view images, and another is synthesizing holographic stereogram. To create and

High-Resolution Light Field Image Acquisition for Holographic Stereogram Printing

2020 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2020
The light field image acquisition for the holographic stereogram printing method is proposed. Cameras capture the high-resolution perspectives while they are shifted; then utilized as sources in the image processing for holographic stereogram printing.

Perceptual Impact of an Animated Holographic Stereogram

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2003
We reported earlier that holographic stereograms are approaching a level of realism typical of other, more mature, graphical media (Kosnik, Previc, Polhamus, 2001). As image quality and realism improve, holograms may offer certain advantages over more conventional communications media.

Anamorphic imagery in holographic stereograms

Optics Communications, 1973
Abstract Horizontal parallax only (HPO) holographic stereograms may exhibit anamorphic imagery in the reconstructed image. We calculated the anamorphic ratio, using geometrical optics, as a function of recording and viewing geometry. an experimental example verifying the calculated results is presented.

3D TV by holographic stereogram (II)

SPIE Proceedings, 2007
Computer holographic stereogram (CHS) is useful for holographic 3D TV because it is constructed from the multi horizontal viewpoint plane images and is compatible to the multi-view point images. Each hologram is recorded as a slit hologram (element hologram) but total viewing area and the number of the element holograms have been limited to some extent

Holographic stereogram printing based on digitally computed content generation platform

OPTO, 2019
In this paper, we have implemented a 3D content generation simulator based on integration of phase-only spatial light modulator (SLM) and LabVIEW software to develop a holographic stereogram printer that consists of a coherent laser, a spatial light ...
