Abstract
Abstract A digitized video system utilizing a spatial light modulator which includes deformable mirror devices to form an image. The image is projected onto a moving surface which intersects each point within a three dimensional space to allow the display of a three dimensional image. Each mirror cell is capable of projecting an individual beam. The individual beams form one portion of an image.
