Abstract
Multiple-reflector ultrawide field of view (UWFOV) systems and methods are provided. In one embodiment, a head-wearable display device includes a frame, a narrow-beam light source fixed with respect to the frame, a UWFOV reflective surface fixed with respect to the frame, and a diverging reflective surface fixed with respect to the frame that is configured to receive light emitted from the narrow-beam light source and reflect the light toward the UWFOV reflective surface to spread the light completely across the UWFOV reflective surface.
Claims15
A head-wearable display device, comprising:
- a frame;
- a narrow-beam light source fixed with respect to the frame;
- an ultra-wide field of view (UWFOV) reflective surface fixed with respect to the frame;
- and
- a diverging reflective surface fixed with respect to the frame that is configured to receive light emitted from the narrow-beam light source and reflect the light toward the UWFOV reflective surface to spread the light across the UWFOV reflective surface, wherein the UWFOV reflective surface is configured to collimate and reflect the light toward a predetermined location.
A method for presenting an image to an eye, comprising:
- emitting, from a narrow-beam light source, light comprising imagery;
- reflecting, by a diverging reflective surface, the light toward an ultra-wide field of view (UWFOV) reflective surface;
- and
- reflecting, by the UWFOV reflective surface, the light toward the eye.
