1. A head-tracking autostereoscopic display, comprising:
a) a light valve display having rows and columns and diagonal lines of pixel elements; b) a head sensing device mounted adjacent to the light valve display for determining a head position of at least one viewer at a viewing plane in front of the light valve display; c) a light panel behind the light valve display, comprising a plurality of light emitting sources, arranged in rows and columns parallel to the rows and columns of the pixel elements of the light valve display; d) a lens array between the light panel and the light valve display, focusing light from the light source through the light valve display toward the viewing plane; e) a computer having an input coupled to the head sensing device, an output coupled to the light panel and an output coupled to the light valve display; wherein the computer is programmed to determine the position of a viewer's head using data derived from the head sensing device, and then to sequentially flash the light emitting sources of the light panel while displaying images on the light valve display, so that right and left stereo images are directed toward the viewer's right and left eyes, respectively, so as to form an autostereoscopic image for a viewer located in or near the viewing plane. |
