Anamorphic imagery in holographic stereograms
Optics Communications, 1973Abstract 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.

13.4: The Realism of Reflection Holographic Stereograms
SID Symposium Digest of Technical Papers, 2001Abstract 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,

Color conical holographic stereogram
Optical Engineering, 1995A new method to record a color holographic stereogram and its application in the synthesis of a conical holographic stereogram are presented. The method consists in recording three rainbow holograms on each slit hologram component of the holographic stereogram.

3D TV by holographic stereogram (II)
SPIE Proceedings, 2007Computer 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

Phase profiles for holographic stereograms
Optical Engineering, 1995The 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.

Internet-based preproduction system for holographic stereograms
Journal of Electronic Imaging, 2001A system has been designed with the aim of helping the communication between a producer of holographic stereograms and users of three-dimensional (3D) computer graphics. The user of the system communicates with the producer through a small program, an applet, which is transferred over the Internet.

Consideration of improvement of electro-holographic stereogram
SPIE Proceedings, 2011Computer 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 ...

Medical applications of holographic stereograms
SPIE Proceedings, 1991A method for displaying 3D images of medical objects by using holographic stereogram is described together with basic properties of reconstructed images of cylindrical holographic stereograms. INTRODUCTI ON A holographic stereogram (HS) is a synthesized hologram from an original film which consists of a series of ordinary photographs taken from ...

Large-format cylindrical holographic stereogram
SPIE Proceedings, 1990To 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 ...
