ABSTRACT:
This invention provides a high efficiency polarized light source and system for the projection of 3D motion pictures adaptable to a standard motion picture projector device. The projected light beam is compressed into a shape more nearly approximating the aperture shape so that substantially less than 40% of the light is lost at the gate.
