Consideration of improvement of electro-holographic stereogram

SPIE Proceedings, 2011
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 ...

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.

Color conical holographic stereogram

Optical Engineering, 1995
A 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.

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 ...

Layered holographic stereogram based on inverse Fresnel diffraction

Applied Optics, 2016
We propose an efficient algorithm using layered holographic stereogram for three-dimensional (3D) computer-generated holograms. The hologram is spatially partitioned into multiple holographic elements (hogels) to provide the occlusion effect and motion parallax by use of multiple viewpoint rendering.

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 ...

Characteristic and improvement on the reconstructed quality of effective perspective images' segmentation and mosaicking-based holographic stereogram.

Applied Optics, 2019
Based on the effective perspective images' segmentation and mosaicking (EPISM) printing method, the influence of the holographic element (hogel) size on the reconstructed quality is analyzed to improve the reconstructed quality of holographic stereogram.

Resolution-enhanced holographic stereogram based on integral imaging using moving array lenslet technique

Applied Physics Letters, 2018
We proposed a resolution-enhanced integral imaging (II) based holographic stereogram (HS) using the moving array lenslet technique (MALT). The HS can be generated fast by Fourier transforming the elemental images of II into hogels.
