HEAD MOUNTED IMAGING APPARATUS WITH CURVED LENSLET ARRAY
First Claim
1. A head-mounted imaging apparatus that comprises:
- a projector that is energizable to project image-bearing light;
a light-conditioning element that directs and shapes the image-bearing light from the projector to form a real image plane;
a lenslet array positioned adjacent to the real image plane and optically disposed at substantially one focal length away from a curved mirror, wherein the surface of the curved mirror is substantially spherical; and
a beamsplitter in the path of light from the real image at the lenslet array and disposed to direct at least a portion of the light from the real image toward the curved mirror;
wherein the curved mirror directs light from the beamsplitter to form a virtual image for an observer who wears the head-mounted imaging apparatus.

Abstract
A head-mounted imaging apparatus has a projector that is energizable to project image-bearing light and a light-conditioning element that directs and shapes the image-bearing light from the projector to form a real image plane. A lenslet array is positioned adjacent to the real image plane and optically disposed at substantially one focal length away from a curved mirror, wherein the surface of the curved mirror is substantially spherical. There is a beamsplitter in the path of light from the real image at the lenslet array and disposed to direct at least a portion of the light from the real image toward the curved mirror. The curved mirror directs light from the beamsplitter to form a virtual image for an observer who wears the head-mounted imaging apparatus.

10. A method for forming a virtual image for an observer, the method comprising:
-
energizing a projector to form a real image at an image plane; positioning a lenslet array adjacent to the image plane and disposed at substantially one focal length away from a curved mirror in the field of view of the observer, wherein the surface of the curved mirror is substantially spherical; and disposing a beamsplitter in the path of light from the real image at the lenslet array to direct at least a portion of the light from the real image toward the curved mirror; wherein the curved mirror directs light from the beamsplitter to form the virtual image for the observer. - View Dependent Claims (11)
