Abstract
Dimension Technologies Inc. has experimentally demonstrated an optical system that produces autostereoscopic images and also allows very high brightness and power efficiency to be achieved using off the shelf color LCDs. This capability is important in applications such as cockpit displays or mobile, portable, or laptop systems where brightness must be maximized but power conserved as much as possible. The effects are achieved through the creation of light line illumination, by means of which autostereoscopic images are produced, and by simultaneously concentrating the light emitted by the display toward the area the viewer's head is. By turning different illumination sources on and off, it is possible to aim both the concentration area and the 3D viewing area at the observer's head as the observer moves. A variation on the system allows two or more persons to be tracked independently. Cross talk (ghosting) can be reduced to the point that imperceptibility can be achieved.
