Abstract
A system (100), apparatus (110), and method (900) for displaying an image (880). The system (100) can use an aspherical lens (450) to direct light (800) in the interim image (850) towards the viewer (96) of the final image (880) displayed by the system (100). Use of the aspherical lens (450) expands the FOV (860) accessible to the viewer (96) and reduces exit pupil drift (480).
