Abstract
A display generates a real image of object pixels, from which an optical system with lenslets generates an immersive virtual image of image pixels, by each lenslet projecting light from the display to a respective pupil range on an imaginary eyeball subtending 15 degrees whole angle at the center of the eyeball. Object pixels are in clusters, each associated with a lenslet that produces from the object pixels a partial virtual image. The partial virtual images combine to form the immersive virtual image. Imaging light rays on the pupil range via a given lenslet come from the associated cluster. Imaging light rays falling on the pupil range from a given cluster pass through the associated lenslet. Imaging light rays exiting a given lenslet towards the pupil range from one image pixel of the immersive virtual image are from a single object pixel of the associated cluster.
