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. This study is concerned with how a message delivered in a hologram

New Methods Of Making Flat Holographic Stereograms

SPIE Proceedings, 1988
In this paper several new methods for making holographic stereograms are presented. Wide angle, white light viewable flat stereograms with higher quality images, i.e, higher resolution, free of distortions and aberrations within a considerable viewing range, could be created.

Medical applications of holographic stereograms

SPIE Proceedings, 1991
A 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 ...

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 ...

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,

Simple real-time 3D holographic stereogram

Proceedings of SPIE, 1995
A display for presenting real-time 3D video or computer generated images is described. The display consists of an LCD panel, two HOEs and a white light source.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.

Numerical reconstruction of full parallax holographic stereograms

3D Research, 2012
Holographic printers based on holographic stereograms are constantly gaining popularity. A holographic stereogram is recorded using 2D images of the 3D object or scene that are captured from multiple perspectives. Separation of capture and recording steps as well as checking of quality of the achieved 3D representation requires replaying of the ...

3D Image Display Using Holographic Stereograms

SPIE Proceedings, 1989
The holographic stereogram is synthesized from a series of ordinary photographs, and is a very attractive medium for displaying 3D images. This paper presents a method of synthesizing a cylindrical hologrphic stereogram with white light reconstruction called multiplex hologram, and fundamental properties of reconstructed images such as distortion and ...

Internet-based preproduction system for holographic stereograms

Journal of Electronic Imaging, 2001
A 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.
