Abstract
A display device includes a display operable to generate a real image and an optical system including: a plurality of optical channel bundles, each bundle comprising one or more channels, each channel comprising a lenslet arranged to generate a sub-image from a respective partial real image on the display, Each lenslet is configured to project light from the display to a corresponding eye position among two eye positions. The sub-images combine to form two virtual images so that different optical channel bundles image a same portion of the display to different portions of the virtual images. The optical system is configured to allow light to flow through selected channels and prevent, light from flowing through other selected channels. The system successively opens the optical channel bundles and displays partial real images associated with the channels of the corresponding optical channel bundle.
