A technique has been developed and demonstrated to present
full color stereoscopic imagery using standard projection display systems.
This polarized color multiplexing technique (patent application filed) does
not require additional image sources beyond those contained within the
original 2-D display system. A full-resolution image is delivered to each
eye, without increasing the video bandwidth of the original display. The
approach separates the primary image colors between right eye and left
eye views and uses polarization to alternate the colors every frame, thus
generating a full color 3-D image on the projection screen. Any stereopair
video source can be used, such as dual cameras, dual VCRs, or computer
generated imagery. Either commercially available or custom threechannel
projection systems (CRT, light valve, or laser) can be transformed
into a stereoscopic display for group viewing.
