<p>A multi-viewer autostereoscopic display system having a viewing field across which the system is capable of steering exit pupils, in each of which a viewer is capable of viewing an image for a selected eye. The system comprises an image forming device for generating an image by selective attenuation of radiation, an array of optical elements for projecting radiation towards the image forming device, and an array of radiation output positions for outputting radiation into the array of optical elements. A plurality of sets of radiation output positions are provided, each set extending over a corresponding horizontal width which is associated with one of the optical elements. The radiation output positions are selectable such that an exit pupil is formed in a selected part of the viewing field by selection of at least one radiation output position from each of the plurality of sets of radiation output positions. Each of the sets of radiation output positions has an associated aperture for limiting the horizontal extent of the light projected from the radiation output positions. The apertures each have a horizontal extent which is less than the horizontal width of the associated set of radiation output positions.</p> |
