ABSTRACT:
A system for producing and displaying spatially-multiplexed images of three-dimensional imagery for use in stereoscopic viewing thereof substantially free of visual-channel cross-talk and stereoscopic asymmetric distortion. The system includes a display device for displaying micropolarized spatially-multiplexed images using a phase-retarding micropolarization structure. The micropolarization structure has phase-retarding characteristics which introduce phase-retardation error to light associated with the micropolarized spatially-multiplexed image at a particular wavelengths in the visible band, and create visual-channel cross-talk. The system also includes a viewing device for viewing the micropolarized spatially-multiplexed images using a phase-retarding polarizer having phase-retarding characteristics which substantially eliminate the phase-retardation error introduced by micropolarization structure during image display, and thus the visual-channel cross-talk and stereoscopic asymmetric distortion.
