Head mounted imaging apparatus with curved lenslet array

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.
