A display device including a display to generate a real image, and an optical system. The optical system includes a plurality of lenslets, each having one cluster of object pixels, where the assignation of object pixels to clusters may change periodically in time intervals. Each lenslet produces a ray pencil from each object pixel of its cluster which has waists laying close to a waist surface. The ray pencils are projected towards an eye position. The ray pencils are configured to generate a partial virtual image from the real image of its corresponding cluster. At least two of the lenslets cannot be made to coincide by a simple translation rigid motion. Foveal rays are a subset of rays emanating from the lenslets.
