Compact wide field of view imaging system
First Claim
1. An optical imaging system comprising:
- a prism having a first face directed toward a display to receive light from the display and direct it through a second face;
a converging optical element between the second face of the prism and the display;
a reflective converging optical element adjacent the second face of the prism to receive the display light through the second face of the prism and reflect it back into the second face of the prism;
a diverging optical element aligned with the reflective converging optical element to receive the display light reflected back into the prism and direct it to an exit pupil.

Abstract
The present invention provides an enhanced viewing eyepiece for a micro-display. In one embodiment, the invention is an optical imaging system that includes a prism having a first face directed toward a display to receive light from the display and direct it through a second face, a converging optical element between the second face of the prism and the display, and a reflective converging optical element adjacent the second face of the prism to receive the display light through the second face of the prism and reflect it back into the second face of the prism, the invention further includes a diverging optical element aligned with the reflective converging optical element to receive the display light reflected back into the first prism and direct it to an exit pupil.
