different views therefore the binocular parallax depth perception cue is reproduced by the given autostereoscopic display furthermore as it is seen from fig2 whenever the observer moves around the static virtual image used in the diagram stays at the same location behind the screen thus the monocular movement parallax is exhibited by the presented display on another hand when the eyes 10 and 11 are focused on the same virtual point 32 then the viewing axis of the two eyes will lye along the lines connecting corresponding eye with the virtual point 32 therefore there is an angle between the two viewing axis of observer 39 s eyes and the convergence depth cue is perceived similarly a virtual point not shown that is a little closer than 32 to the observer 39 s eyes 10 and 11 will appear out of focus when the eyes are focused on the point 32 thus accommodation depth cue is exhibited by the presented autostereoscopic display 0057 fig2 shows a large scale view of part of the autostereoscopic display apparatus it shows one lens 21 an aperture 22 and part of the spatial light modulator 20 that presumably displays one elemental image of a modulating photogram there are four stages 25 26 27 and 28 that the light from the back lighting means travels through stage 25 is a stage where in the preferred embodiment of the invention the light 4 is collimated and.
