Abstract
AbstractIn this paper, a glasses‐free (autostereoscopic) display is described where the controlled illumination for a liquid crystal display (LCD) backlight is derived from a laser source where the laser is used not for its coherence properties but for its ability to have close control on its direction. This allows light exiting the LCD to be directed to the left and right eyes of several viewers who can move freely in both the X and Z directions. Light directions are determined by a spatial light modulator (SLM) that is controlled by a multiuser head tracker. This paper is principally concerned with the SLM and the Gabor superlens screen that is used to provide the angular magnification required to give a sufficiently wide viewing field,
