Three dimensional virtual and augmented reality display system
First Claim
1. A three-dimensional image visualization system, comprising:
- an integrated module comprising;
a selectively transparent projection device configured to receive input image light and configured to project an image associated with the input image light 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; and
a diffraction element coupled to the selectively transparent projection device and configured to divide the input image light into a plurality of modes, each of the plurality of modes directed at a different angle,wherein the selectively transparent projection device is configured to allow at least a first mode of the plurality of modes to exit the selectively transparent projection device toward the eye, the first mode having a simulated focal distance based in part on a selectable geometry of the diffraction element, andwherein the selectively transparent projection device is configured to trap at least a second mode of the plurality of modes within the selectively transparent projection device;
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 occlusion mask from the eye of the viewer in an occluding pattern correlated with the image projected by the projection device; and
a controller operatively coupled to the integrated module and the occlusion mask device, and configured to coordinate projection of the image and associated occluding pattern, as well as interposition of the diffraction pattern at the selectable geometry.

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.
