Lenticular autostereoscopic display system: multiple images for multiple viewers

This paper describes a 2.5-m (100-in.) lenticular autostereoscopic display system. In this system, multiple viewers can simultaneously observe their own images on the same screen with motion parallax according to their eye positions. The viewable areas of this system are extended by introducing head-position tracking that uses an infrared illuminated stereo measurement method. This paper explains the operating principles of the proposed system and discusses the design of a lenticular screen for multiple viewers by giving consideration to spatial resolution, side-lobe width, and thickness of the screen's substrate as a function of focal length. An experimental prototype of the proposed system is also shown. Finally, the width of the viewable area and the crosstalk between images for the left eye and those for the right eye are analyzed, and the performance of the head-position tracking is evaluated.
