Stereographic projection system
First Claim
1. A projection system configured to project a stereographic image onto a viewing surface, the stereographic image including a left-eye image and a right-eye image, the projection system including:
- a light source configured to produce a beam of light;
a beam splitter configured to split the beam of light into a right image beam and a left image beam;
an image engine configured to produce the stereographic image, the image engine including a left optical path configured to produce the left-eye image from the left image beam, the left optical path including an upstream left polarizer, a left image-producing element and a downstream left polarizer, and a right optical path configured to produce the right-eye image from the right image beam, the right optical path including an upstream right polarizer, a right image-producing element and a downstream right polarizer; and
a projection lens configured to project the left-eye image and the right-eye image onto the viewing surface.

Abstract
A projection system configured to project a stereographic image onto a viewing surface is provided. The projection system includes a light source configured to produce a beam of light, a beam splitter configured to split the beam of light into a right image beam and a left image beam, an image engine configured to produce the stereographic image, and a projection lens configured to project a left-eye image and a right-eye image onto the viewing surface. The image engine includes a left optical path configured to produce the left-eye image from the left image beam, the left optical path including an upstream left polarizer, a left image-producing element and a downstream left polarizer, and a right optical path configured to produce the right-eye image from the right image beam, the right optical path including an upstream right polarizer, a right image-producing element and a downstream right polarizer.

15. A desktop projection system configured to project a stereographic image onto a viewing surface, the stereographic image including a left-eye image and a right-eye image configured to be perceived as a single three-dimensional image by a viewer, the projection system comprising:
-
a body;
a light source disposed within the body, the light source being configured to produce a beam of light;
a beam splitter disposed within the body, the beam splitter being configured to split the beam of light into a left image beam and a right image beam;
a left image-producing disposed within the body, the left image-producing element being configured to produce the left-eye image when illuminated by the left image beam;
a right image-producing element disposed within the body, the right image-producing element being configured to produce the right-eye image when illuminated by the right image beam; and
a projection lens configured to project the left image beam and right image beam onto the viewing surface. - View Dependent Claims (16, 17, 18, 19)
