1. A system for visually presenting a pair of spectrally-multiplexed images of a three-dimensional scene for use in stereoscopic viewing thereof by a viewer having left and right eyes, said system comprising:

  • image display means for sequentially displaying a first spectrally-multiplexed image during a first display period and a second spectrally-multiplexed image during a second display period, said first spectrally-multiplexed image having a first group of spectral components obtained from a first perspective image of said three-dimensional scene and a second group of spectral components obtained from a second perspective image of said three-dimensional scene, and said second spectrally-multiplexed image having a second group of spectral components obtained from said first perspective image of said three-dimensional scene and a first group of spectral components obtained from said second perspective image; and

    electro-optical image processing apparatus, disposed between said image display means and the left and right eyes of the viewer, for alternatively processing said first and second spectrally-multiplexed images as said first and second spectrally-multiplexed images are visually presented to the left and right eyes of the viewer by said image presentation means, said electro-optical image processing means being operable during said first display period for processing said first spectrally-multiplexed image so as to selectively transmit only the first group of spectral components of said first perspective image to the left eye of the viewer and only the second group of spectral components of said second perspective image to the right eye of the viewer during said first display period, and said electro-optical image processing apparatus being operable during said second display period for optically processing said second spectrally-multiplexed image so as to selectively transmit only the second group of spectral components of said first perspective image to the left eye of the viewer and only the first group of spectral components of said second perspective image to the right eye of the viewer during said second display period,whereby the first and second groups of spectral components of said first perspective image are transmitted from said image display means to the left eye of the viewer over said first and second display periods, and the first and second groups of spectral components of said second perspective image are transmitted from said image display means to the right eye of the viewer over said first and second display periods so that said three-dimensional scene can be stereoscopically viewed by the left and right eyes of the viewer.
