Image-plane cylindrical holographic stereogram

Applied Optics, 2000
A two-step holographic process is introduced to fabricate a cylindrical multiplex hologram as an image-plane hologram. By adoption of the achromatic angle in the process the hologram is capable of generating an achromatic image. The most important factors, the location as well as the width of the viewing slits, that affect the quality of the observed ...

Conical holographic stereograms

Optics Communications, 1989
Abstract Methods for making conical holographic stereograms are developed for monochromatic light and white light reconstructions, and real and virtual image reconstructions. One of the advantages of a conical holographic stereogram is the possibility to reconstruct real images with a simple parallel white light illumination.

Computer-Generated Holographic Stereograms

Advances in Imaging, 2009
We examine one type of holographic stereogram and its implementation on two widely different media. The first medium is photoresist for a conventional computer-generated hologram. The second medium is photo-refractive polymer for re-writable holograms.

Reflection Holographic Stereograms

Topical Meeting on Holography, 1986
The principles of achromatic holographic stereograms are extended to reflection format, based on a simple model of wide-band, volume-phase reflection holograms.

Holographic Stereograms in Assemblage

Leonardo, 1983
The author gives a brief description of holographic stereograms and their characteristics as they relate to his work. He recalls how motion captured in these 3-dimensional, light-formed images suggest ed new possibilities for his work in assemblage.

Continuous Recording of Holographic Stereograms

Digital Holography and Three-Dimensional Imaging 2019, 2019
We achieve the continuous recording and refreshing of holographic stereograms by replacing the translation stage scanning the holographic screen with a belt system holding flexible holographic lenses. This system is removing one of the roadblocks standing in the pathway of 3D videorate holographic display.

Use Of A Holographic Lens For Producing Cylindrical Holographic Stereograms

Optical Engineering, 1981
The production of cylindrical holographic stereograms, or multiplex holograms, requires the use of a large, low f/number cylindrical lens to form a line image on the holographic film. To have an image of reasonable size for display purposes, the f/number of the lens must be quite small, on the order of f/1, and the dimensions of the lens must be ...

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.

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 ...

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
