Abstract
Left eye and right eye images of an autostereoscopic display are displayed on LCD spatial light modulators which are illuminated by movable light sources via converging lenses or mirrors. A tracking system tracks the position of an observer and a control system controls the positions of the light sources so that the images of the light sources formed by the lenses or mirrors track the observer. The observer thus sees the 3D image while having an enlarged degree of freedom of movement.
