Abstract
Most of the previously-tried prototype systems of digital holographic display are of front viewing flat panel-type systems having narrow viewing angle, which do not meet expectations towards holographic displays having more volumetric and realistic 3-dimensional image rendering capability. We have developed a tabletop holographic display system which is capable of 360° rendering of volumetric color hologram moving image, looking much like a real object. Multiple viewers around the display can see the image and perceive very natural binocular as well as motion parallax. We have previously published implementation details of a mono color version of the system, which was the first prototype. In this work, we present requirements, design methods, and the implementation result of a full parallax color tabletop holographic display system, with some recapitulation of motivation and a high-level design concept. We also address the important issue of performance measure and evaluation of a holographic display system and image, with initial results of experiments on our system.
Highlights
Digital electroholographic display technology has been believed to be an ultimate solution for3-dimensional displays due to its theoretically perfect 3-dimensional visual cue support without any conflict among them
We report on the enhanced version of the system, which is full-color, full parallax with extended vertical viewing range, and address initial experimental result of performance measurement and evaluation of the system
(2) The image should be seen by multiple viewers at at thethe same time, 2) hologram
Summary
Digital electroholographic display technology has been believed to be an ultimate solution for. 3-dimensional displays due to its theoretically perfect 3-dimensional visual cue support without any conflict among them. We can categorize the realization of electronic dynamic holographic displays into two groups: one is a flat panel-based direct front viewing type and the other is tabletop type which renders volumetric 3D images floating on or above the display. Holograms and holographic displays are expected to have more powerful
