ABSTRACT:
A method is disclosed for projecting a pair of stereoscopic pictures (10, 11 or 23, 27) which can be seen in three dimensions without the observer (22) wearing special spectacles or using other optical aids. The system is adapted to be practical with relatively large screens (18, 30) in very compact forms including use as a table top computer display or in other restricted cabinets. The combination includes a pair of adjacent large projection optics (14, 15 or 28, 29) and a beam splitter (16, 26) capable of both light transmission and light reflection and which is positioned twice in the light path (12, 13) from the source to the observer, and which is particularly suited for compact forms of the device. Also included is a special screen (18, 30) which also has focus power and casts an image (19, 20) of the pair of adjacent projection optics (14, 15) out in space as an adjacent pair of limited viewing areas for an observer's eyes (22) to see the pair of stereoscopic pictures separately, one with each eye, so he can see them as a three dimensional picture without wearing special glasses.
