Abstract

A system may comprise a selectively transparent projection device for projecting an image toward an eye of a viewer from a projection device position in space relative to the eye of the viewer, the projection device being capable of assuming a substantially transparent state when no image is projected; an occlusion mask device coupled to the projection device and configured to selectively block light traveling toward the eye from one or more positions opposite of the projection device from the eye of the viewer in an occluding pattern correlated with the image projected by the projection device; and a zone plate diffraction patterning device interposed between the eye of the viewer and the projection device and configured to cause light from the projection device to pass through a diffraction pattern having a selectable geometry as it travels to the eye.

First claim

The invention claimed is:

1. A three-dimensional image visualization system, comprising:
a. a selectively transparent projection device for projecting an image toward an eye of a viewer from a projection device position in space relative to the eye of the viewer, the projection device being capable of assuming a substantially transparent state when no image is projected;
b. an occlusion mask device coupled to the projection device and configured to selectively block light travel…
