A display device comprising: a digital display, operable to generate a real image comprising a plurality of object pixels,,,; and an optical system, comprising an array of a plurality of lenslets,,, arranged to generate an immersive virtual image from the real image, the immersive virtual image comprising a plurality of image pixels, by multiple lenslets of the plurality of lenslets projecting light from the display with each lenslet of the multiple lenslets projecting light to a respective pupil range; wherein the pupil range of a given lenslet of the multiple lenslets comprises a region on the surface of an imaginary sphere of diameter from 21 to 27 mm, the pupil range of the given lenslet including at least a circle subtending 15 degrees whole angle at the center of the sphere; wherein the object pixels are grouped into clusters,,,, each cluster associated with a lenslet of the multiple lenslets, so that the associated lenslet produces from the object pixels a partial virtual image comprising image pixels, and the partial virtual images combine to form said immersive virtual image; wherein, when the display device is worn by a user, each of the partial virtual images contains a part projected by an eye's optics onto a 1.5 mm diameter fovea of said eye when said eye is at the position of the imaginary sphere with its pupil within the associated pupil range, said part of each said virtual image having a higher resolution than a peripheral part; wherein substantially all imaging light rays falling through the given lenslet of the multiple lenslets on its respective pupil range come from pixels of the associated cluster, and substantially all said imaging light rays falling on said respective pupil range from object pixels of a given cluster pass through the associated lenslet; wherein substantially all said imaging light rays exiting the given lenslet of the multiple lenslets towards its respective pupil range and virtually coming from any one image pixel of the immersive virtual image are generated from a single object pixel of the associated cluster. wherein pixels of different clusters that display the same pixel of the visual image are linked into a web; and wherein all the object pixels of one web are caused to display the same information. a digital display, operable to generate a real image comprising a plurality of object pixels,,,; and an optical system, comprising an array of a plurality of lenslets,,, arranged to generate an immersive virtual image from the real image, the immersive virtual image comprising a plurality of image pixels, by multiple lenslets of the plurality of lenslets projecting light from the display with each lenslet of the multiple lenslets projecting light to a respective pupil range; wherein the pupil range of a given lenslet of the multiple lenslets comprises a region on the surface of an imaginary sphere of diameter from 21 to 27 mm, the pupil range of the given lenslet including at least a circle subtending 15 degrees whole angle at the center of the sphere; wherein the object pixels are grouped into clusters,,,, each cluster associated with a lenslet of the multiple lenslets, so that the associated lenslet produces from the object pixels a partial virtual image comprising image pixels, and the partial virtual images combine to form said immersive virtual image; wherein, when the display device is worn by a user, each of the partial virtual images contains a part projected by an eye's optics onto a 1.5 mm diameter fovea of said eye when said eye is at the position of the imaginary sphere with its pupil within the associated pupil range, said part of each said virtual image having a higher resolution than a peripheral part; wherein substantially all imaging light rays falling through the given lenslet of the multiple lenslets on its respective pupil range come from pixels of the associated cluster, and substantially all said imaging light rays falling on said respective pupil range from object pixels of a given cluster pass through the associated lenslet; wherein substantially all said imaging light rays exiting the given lenslet of the multiple lenslets towards its respective pupil range and virtually coming from any one image pixel of the immersive virtual image are generated from a single object pixel of the associated cluster. wherein pixels of different clusters that display the same pixel of the visual image are linked into a web; and wherein all the object pixels of one web are caused to display the same information.
