POLARIZING SYSTEM FOR MOTION VISUAL DEPTH EFFECTS

A system for creating the perception of visual depth in two dimensional single image displays. A polarizing projection filter 1c provides means to control the plane of polarization of projected imagery. The plane of polarization is changed by changing the orientation of the polarizing projection filter. An observer wears special viewing glasses 2 with polarizing filters when viewing imagery polarized by the polarizing projection filter. The plane of polarization of the polarizing viewing filter for the right eye 3 is oriented 30 degrees clockwise from horizontal. The plane of polarization of the polarizing viewing filter for the left eye 4 is oriented 30 degrees counterclockwise from horizontal. When the polarizing projection filter has an angular offset of approximately 45 degrees clockwise from horizontal the projected imagery appears approximately 20 times brighter to an observer's right eye than to the observer's left eye. Objects moving laterally 9 from right to left from the observer's perspective appear closer to the observer 10. Objects moving from left to right appear farther away from the observer. When the polarizing projection filter has an angular offset of approximately 45 degrees counterclockwise from horizontal the projected imagery appears approximately 20 times brighter to an observer's left eye than to the observer's right eye. Objects moving from right to left from the observer's perspective appear farther away from the observer. Objects moving from left to right appear closer to the observer. The imagery can be viewed in full color. The dead eye effect can be avoided by periodically changing the plane of polarization of the polarizing projection filter.
