Electronic Tabletop Holographic Display: Design, Implementation, and Evaluation

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.

Development of Real-Time Hand Gesture Recognition for Tabletop Holographic Display Interaction Using Azure Kinect

“…Tabletop holographic display is a device that allows the viewer to observe 3D hologram contents created from various angles with multiple cameras and view them anywhere from 360 degrees [14][15][16]. The system allows multiple viewers to view digital hologram images in the horizontal 360-degree direction by using digital micromirror device (DMD) capable of high-speed operation as a spatial light modulator (SLM).…”

Holographic display in future automotive smart cockpit: application scenarios, interaction modals, and VACP analysis

“…Looking Glass Portrait in 2018 provides a full-color holographic display solution with 7.9" display volume, up to 100 views and 58° viewing cone. Jinwoong Kim et al get deep into electronic tabletop holographic display from 2017, and produced their demonstration device with SLM module and eye-tracking camera 10 . Besides, negative refraction slab lens is also welcome 11 , especially by commercial solutions in China and Japan.…”

Enlargements of Viewing Zone and Screen Size of Holographic Displays Using MEMS SLM Combined with Scanning Systems

“…FOR PEER REVIEW 7 of 14 became redder when they were viewed from the left side and more cyan when they were viewed from the right side. The generation of 3D color image using MEMS SLMs has been proposed by numerous research groups [15,21,26]. There are two techniques that can be used to generate 3D color images: the time-multiplexing technique using a single MEMS SLM and the space-multiplexing technique using three MEMS SLMs.…”
