Conjugate optics projection display with image enhancement
First Claim
1. A method of displaying information, comprising projecting an image in overlaid relation on an actual view of an object, wherein the image is from a same point of view as the actual view, and is of at least part of the actual view or of a missing part of the actual view.

Abstract
A projected image is overlaid on an actual view of an object, the image being identical to the actual view in size, shape and scale, and being perfectly registered with the actual view, e.g, as to position or location, and, accordingly being substantially parallax-free. The image may be of different “color” than the actual view, i.e., one may be a view or image of light in a visible wavelength region, band or bandwidth, and the other may be a view or image in a non-visible wavelength region, band or bandwidth, such as a view or image of infrared light or of x-ray radiation. The infrared view or image may be converted to a view or image in the visible bandwidth for viewing by a person. The image mentioned above may be a real image of an actual view of an object, scene or the like. Alternatively, the image may be an image other than of an actual view of an object, for example being a previously-obtained image along a same or similar point of view as the actual view of the object, scene, or the like. As another example, the image may be a computer-generated image based on previously-obtained data regarding the object, scene, or the like. The image may be an image obtained by a camera or some other means and then delivered, e.g., as by projection via a projector and conjugate optics, for superpositioning with respect to the real or actual view for viewing by a user.

11. A system for enhancing vision comprising
means for obtaining an actual view of an object from a point of view, means for obtaining an image of an actual part or a missing part of the actual view from the point of view; - and
means for superimposing said the image on the actual view such that the image enhances viewing of the object, the means for superimposing including imaging and projecting means for projecting in a conjugate path the image;
wherein as viewed the actual view and the image are separated by spectral region or by computer generation. - View Dependent Claims (12, 13, 14, 15, 16, 33, 36)

17. A method of displaying information, comprising,
projecting an image in overlaid relation on an actual view of an object, wherein the image is obtained in a non-visible spectrum and the actual view of the object is obtained or provided in the visible spectrum, the actual view of the object and the image being from a same point of view.

18. A system for enhancing vision comprising:
-
a beamsplitter which allows a view of an object to at least partially pass therethrough; and
a projector which projects onto the beamsplitter an image that represents, from a same point of view as the view of the object, an actual part or a missing part of the view, such that at least part of the image is superimposed on the view of the object. - View Dependent Claims (19, 20, 21, 22, 23, 27, 30, 31, 32, 37, 38)

24. A system for enhancing vision comprising:
-
a beamsplitter which allows a view of an object to at least partially pass therethrough;
a projector which projects onto the beamsplitter an image that represents an actual part or a missing part of the object as viewed, such that at least part of the image is superimposed on the view of the object; and
a detector which receives at least some of a reflected portion of the view of the object which is reflected by the beamsplitter, the detector being operatively coupled to the projector to provide data to the projector for use in projecting the image. - View Dependent Claims (25, 26, 35, 39, 40)

28. A system for enhancing vision comprising:
-
a first beamsplitter which allows a view of an object to at least partially pass therethrough, a projector which projects onto the first beamsplitter an image that represents an actual part or a missing part of the view of the object, such that at least part of the image is superimposed on the view of the object, a second beamsplitter optically coupled to the first beamsplitter, a third beamsplitter optically coupled to the first and second beamsplitters, and a retroreflector optically coupled to the third beamsplitter, wherein the third beamsplitter and the retroreflector are a substantial distance away from the detector and the projector. - View Dependent Claims (29)
