Abstract
A method and apparatus for a single panel projector, for projecting images having a plurality of color components, include a mechanism for deflecting light into a plurality of directions, and a light panel for receiving the light deflected by the deflecting mechanism. The deflecting mechanism includes a transparent optical medium having a nonuniform thickness, in which light beams enter through a center opening of the medium and exit at areas along a side of the medium.
