HEAD-MOUNTED OPTICAL APPARATUS USING AN OLED DISPLAY
First Claim
1. A see-through head-mounted optical apparatus for a viewer comprising at least one display module, each display module comprising:
- a display that is energizable to form an image;
a positive field lens optically coupled to the surface of the display and disposed to direct imaged light from the display toward a first surface of a prism; and
a curved reflector element in the path of the imaged light through the prism and disposed adjacent to a second surface of the prism, opposite the first surface,the curved reflector element comprising a refractive surface and a curved reflective surface that is disposed to collimate imaged light received from the display and direct this light toward a beam splitter that is disposed within the prism and that is at an oblique angle to the collimated reflected light;
wherein the beam splitter redirects the incident collimated reflected light through the prism to form an entrance pupil for the viewer.

Abstract
A see-through head-mounted optical apparatus for a viewer has at least one display module, each display module having a display energizable to form an image and a positive field lens optically coupled to the surface of the display and disposed to direct imaged light from the display toward a first surface of a prism. A curved reflector element is in the path of the imaged light through the prism and disposed at a second surface of the prism, opposite the first surface. The curved reflector element has a refractive surface and a curved reflective surface disposed to collimate imaged light received from the display and direct this light toward a beam splitter that is disposed within the prism and that is at an oblique angle to the collimated reflected light. The beam splitter redirects the incident collimated reflected light through the prism to form an entrance pupil for the viewer.

13. A see-through head-mounted optical apparatus for a viewer comprising a left-eye display module and a right-eye display module, each display module comprising:
-
an emissive display that is energizable to form an image; a positive field lens that comprises optical fibers and is optically coupled to the surface of the display and is disposed to direct imaged light from the display toward a first surface of a prism; a curved reflector element in the path of the imaged light through the prism and disposed adjacent to a second surface of the prism, opposite the first surface, the curved reflector element comprising a refractive surface that is optically coupled to the second surface of the prism and a curved aspheric reflective surface that is disposed to collimate imaged light received from the display and direct this light toward a beam splitter that is disposed within the prism and that is at an oblique angle to the collimated reflected light; wherein the beam splitter redirects the incident collimated reflected light through the prism to form an entrance pupil for the viewer. - View Dependent Claims (14, 15, 16)

17. A method for providing a see-through head-mounted display, the method comprising:
-
energizing a display to form an image; directing imaged light from the display toward a first surface of a prism through a positive field lens that is optically coupled to the surface of the display; collimating the imaged light at a curved reflective surface that is disposed adjacent to a second surface of the prism, opposite the first surface, and directing the collimated imaged light toward a beam splitter that is disposed within the prism and that is at an oblique angle to the collimated reflected light; and forming an entrance pupil for the viewer. - View Dependent Claims (18, 19)
