1. A full-spectrum stereoscopic display system, without requiring color separation between left-eye and right-eye views, for presenting a first and second full-spectrum image of a stereo pair of images to the left and right eyes of a viewer so that the viewer can perceive a three-dimensional image, comprising:

  • a display image comprising a pattern of alternating first and second regions, said first regions displaying the full-spectrum image from corresponding regions of said first full-spectrum image of said stereo pair, and said second regions displaying the full-spectrum image from corresponding regions of said second full-spectrum image of said stereo pair, said first and second regions selected through transparent regions of a tiling mask and its inverse respectively;

    a polarized mask patterned with the same said pattern of alternating first and second regions, said first regions containing a first polarizer of a first orientation, and said second regions containing a second polarizer of a second orientation, said polarized mask positioned between said display image and said viewer and positioned so that said pattern of said polarization mask appears overlayed and aligned to said pattern of said display image; and

    polarized viewing glasses, with first and second polarized filter lenses in front of said left and right eyes of said viewer, said first polarized filter lens being in said first orientation and said second polarized filter lens being in said second orientation;

    wherein, said first full-spectrum image from said first regions of said display image travels through said first regions of said polarized mask and through said first polarized filter lens of said viewing glasses to reach said left eye, while said second full-spectrum image from said second regions of said display image travels through said second regions of said polarized mask and through said second polarized filter lens of said viewing glasses to reach said right eye.
