Paraxial stereoscopic projection system
First Claim
1. A stereoscopic projection system for viewing from an eye station a stereoscopic image comprising:
- a pair of image sources each having an image center which are spaced-apart from each other;
a concave spherical mirror segment having a center of curvature and located between said image source pair and said viewable stereoscopic image which also has an image center, and being disposed so that said image centers of said image source pair and said viewable stereoscopic image are located at said center of curvature;
image deflecting means disposed between each image source and said spherical mirror about the juncture whereat the aperture of the system is the smallest so that the image center of each of said image sources are located in spaced-apart relationship; and
beam splitter means interposed to reflect image projection between said deflecting means and said spherical mirror and to pass image projection between said spherical mirror and said eye station.

Abstract
Disclosed is a stereoscopic projection system for viewing from an eye station a stereoscopic image composed of a 1 x magnification of an image source pair. Said system comprises a pair of image sources each having an image center which are spaced apart from each other; a concave spherical mirror segment having a center of curvature and located between said image source pair and said viewable stereoscopic image. The concave spherical mirror is disposed so that the image centers of said image source pair and said viewable stereoscopic image are located at said center of curvature. Image deflecting means are disposed between its image source and said spherical mirror about the juncture whereat the aperture of the system is the smallest so that the image center of each of said image sources are located in spaced apart relationship. Finally, a beam splitter is interposed to reflect image projection between said deflecting means and said spherical mirror and to pass image projection between said spherical mirror and said eye station.

5. A method for projecting a stereoscopic image for viewing from an eye station wherein said image comprises an image source pair, which comprises:
-
providing a pair of image sources each having an image center which are spaced apart from each other; locating a concave spherical mirror segment having a center of curvature between said image source pair and said viewable stereoscopic image which also has an image center, said mirror segment being disposed so that said image centers of said image source pair and said viewable stereoscopic image are located at said center of curvature; disposing image deflecting means between each image source and said spherical mirror about the juncture whereat the aperture of the system is the smallest so that the image center of each of said image sources are located in spaced-apart relationship; and interposing beam splitter means to reflect image projection between said deflecting means and said spherical mirror and to pass image projection between said spherical mirror and said eye station. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
