Abstract
Over the past two years, DTI has developed technology under an SBIR program designed to create advanced autostereoscopic hologram-like displays yielding multiple full resolution perspective images that can be viewed passively by multiple observers across a wide area. The first prototype display of this type was completed in 1994. It demonstrated three key technologies necessary for the practical embodiment of an advanced commercial flat panel autostereoscopic display. (1) A fast surface mode LCD capable of displaying 180 images per second with many gray levels. (2) An interlaced light line illumination system that is responsible for making different images visible from different regions of space in front of the display, and allows flicker free imaging at near 30 fps. (3) A controller designed to accept perspective images in standard formats, interlace them, and display them on the LCD. These technologies are demonstrated on an 800 X 400 LCD with 32 true gray shades, yielding up to six perspective views every 33 ms. At half resolution it would be possible to generate twelve views. The system is driven by an entry level workstation and could also accept input from multiple cameras, given the right interface. Results of the project and plans for the future will be discussed.
