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.

Computer generated color rainbow holographic stereogram

Journal of Optics, 2022
Abstract In this research, a fast method to calculate the color rainbow holographic stereogram (CRHS) by taking full advantage of the sparsity of the frequency domain is demonstrated. The CRHS is a novel color rainbow hologram containing a large number of elemental CRHSs, where each elemental CRHS only reproduces the color light field

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.

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

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.

Large-format cylindrical holographic stereogram

SPIE Proceedings, 1990
To display 3-D images stored in computer, cylindrical holographic stereograms with white light illumination (CHS) is useful because of both one step synthesis and wide viewing angle in the horizontal direction. But it has been difficult to make the vertical size of reconstructed images larger than 20 cm, because conventional optical system for ...

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.

Three-dimensional TV using holographic stereogram

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 camera stereoscopic image. 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 ...
