Abstract
Official abstract text for this publication.
An apparatus for displaying a 3-dimensional (3D) image, which is capable of providing a super multi-view, is provided. The apparatus includes: at least one image projector for projecting light including an image; an active optical element for adjusting a path of at least one light within a range of a predetermined angle; and a relay optical system for transmitting the at least one light to a pupil of a viewer. The apparatus provides a plurality of images in different views to the pupil using a time division method, by using the active optical element for adjusting the path of the at least one light.
First claim
Opening claim text (preview).
What is claimed is: 1. A three-dimensional (3D) image display apparatus, comprising: an active optical element configured to be switched to have different configurations to adjust the path of light beams defining different perspectives of a single image by refracting the light beams in a time sequential manner; and a relay optical system configured to transmit the refracted light beams towards a pupil of a viewer, wherein first and second perspectives of the image are simultan…
