Analysis of resolution limitation of a glasses-free tabletop 3-Ddisplay

摘要

In this research we investigate the maximum displayable angular resolutions in the horizontal and vertical direc-tions of a planar 3-D object displayed by a glasses-free tabletop 3-D display that is using a conic-shaped optical device and an array of projectors. We estimate initially the resolutions of the (1) slit-like views corresponding to each projector's image and then continue with the resolution for the (2) final 3-D image obtained after the integration of the slits. Our experimental results represent a first attempt in estimating the differences between these resolutions that can benefit (1) future tunings of the tabletop 3-D display as well as (2) optimization of the displaying process.
