Horizontal-parallax-only light-field display with cylindrical symmetry

摘要

Recently, various light-field displays with special structures have been suggested. Among them, the cylinder-shaped display has distinct advantages in providing 360-degree field of view. In this paper, we propose a cylindrical light-field display which consists of panoramic projection optics and a cylindrical screen with several long vertical narrow openings. The projected scene is imaged on the inner surface of the cylinder and the contents are watched through the slit on the side of the cylinder during it rotates. Therefore, horizontal-parallax-only light field is formed to display three-dimensional contents inside of the cylinder.
