Abstract
A method for constructing a stereoscopic light recycling device is provided. At least one support member is affixed to a beam splitter positioned at an angle and constructed of orthogonally polarizing material on which image light is received. A phase shifting optic having a reflective surface coated by a phase shifting film is positioned at an angle non-perpendicular to at least a portion of the image light from the beam splitter. The phase shifting optic includes one of a uniform and non-uniform surface.
