Abstract

A system for projecting stereoscopic images is provided. The system includes a light source configured to provide light energy to a length of film having frames each comprising two sideframes oriented off axis, or side-by-side, from a preferred viewing orientation, an image receiving lens configured to receive light energy transmitted through the length of film, and an optical arrangement configured to receive images as light energy from the image receiving lens. The optical arrangement may include an afocal extender and means for reorienting images to the preferred viewing orientation and registering images reoriented to the preferred viewing orientation to a screen. The means for reorienting and registering include a plurality of optical refractive elements. Polarization, such as linear polarization, may be employed.
