Abstract
A stereoscopic light recycling device is provided. A beam splitter is constructed of substantially orthogonally polarizing material on which divergent image light is received and is positioned at an angle to a source of the divergent image light. A phase shifting optic includes a reflective surface coated by a phase shifting film and is positioned at an angle non-perpendicular to at least a portion of the image light from the beam splitter. The angle of the phase shifting optic is dependent on the angle of the beam splitter.
