چکیده

An autostereoscopic display system, which allowed multiple viewers simultaneously by use of head-tracking, was previously demonstrated for TV applications in the ATTEST project. However, the requirement for a dynamically addressable, movable backlight presented several problems for the illumination source. In this paper, the authors demonstrate how the use of a novel laser-based holographic projection system can be used to address these problems.

Multi-Phase Convex Lens Array for Directional Backlights to Improve Luminance Distribution of Autostereoscopic Display

We realize homogenous luminance of the directional backlight for the time-division multiplexing autostereoscopic display using a convex lens array with the elemental lenses whose phase of placement in each row differs from one another. The validity of the proposed optical design is confirmed by a prototype system. key words: autostereoscopic display, homogeneous brightness, liner Fresnel lens a...

Viewing zone of an autostereoscopic display with a directional backlight using a convex lens array

When a directional backlight to each eye alternates synchronously with the alternation of left-eye and right-eye images on the display panel, the viewer can see a stereoscopic image without wearing special goggles. One way to realize a directional backlight is to place a convex lens array in front of dot matrix light sources to generate collimated light. To implement this method, however, defoc...

Multi–view Autostereoscopic 3d Display

Autostereoscopic displays provide 3D perception without the need for special glasses or other head gear. Three basic technologies exist to make such displays: spatial multiplex, multi-projector and time-sequential. These can be used to make two types of useful device: two-view, head-tracked displays; and multi-view displays. The former tend to be single-viewer systems while the latter can suppo...

Exemplary Test Design and Evaluation of an Autostereoscopic 3DTV considering Display Operating Parameters

This paper addresses the influences of standard operating parameters like backlight, contrast, sharpness, etc. of an autostereoscopic display on subjective quality, in the absence of transmission quality impairments (best case reference). Therefore, a useful test environment is specified and applied. Results show that the influences of different display setups are distinguishable from each othe...

Autostereoscopic and Haptic Visualization for Space Exploration and Mission Design

We have developed a multi-modal virtual environment set-up by fusing visual and haptic images through the use of a new autostereoscopic display and a force-feedback haptic device. Most of the earlier visualization systems that integrate stereo vision and touch have utilized polarized or shutter glasses for stereovision. In this paper, we discuss the development stages and components of our set-...
