Alternative Approach to 3D Displaying

A method for displaying volumetric images, which exploits our binocular vision and does not require eyewear, is discussed. The display can be rendered as a matrix of pivoting micromirrors irradiated by a light beam; each micromirror focuses its pixel beams to the same point of displayed volumetric image. 3D perception of image can be achieved by scanning the point of beams intersection over a virtual surface of displayed image in space.
