ABSTRACT:
There is disclosed a system for the stereoscopic imaging of right and left stereoscopic optical images as these images are projected and displayed on a screen or video monitor. The system uses encoded right and left stereoscopic images with corresponding decoding right and left filters through which the stereoscopic image is viewed. Either polarized or monochromatic light can be used as the right and left image coding medium. A thin face Fresnel prism is positioned between the observer or observers and the projected or displayed right and left stereoscopic images and is located to fuse the two images so that, when they are observed through the decoding filters, an illusion of a three dimensional object is created. For maximum clarity, the Fresnel prism can be vibrated parallel to the original imaging surface.
