Abstract
A display system for realizing concentric light field with monocular-to-binocular hybridization, and methods thereof. At least some embodiments include a display arranged to emit or transmit light rays based on image content from a content engine, and an optical subsystem arranged to configure the light rays into a concentric light field. The concentric light field provides a virtual image in a large, contiguous spatial region, such that each eye of the human viewer can detect monocular depth from the light field, to provide a large field of view.
Claims20
A display system comprising:
- a display arranged to emit or transmit light rays collectively forming a first image;
- and
- an optical subsystem optically coupled to the display and arranged to configure the light rays from the display into a single contiguous light field that forms a virtual image based on the first image and that simultaneously encompasses both eyes of a human viewer when the human viewer is viewing the virtual image, such that an apparent size of the display to the human viewer is at least twice an actual size of the display while the display and the optical subsystem are positioned at least 10 cm from the eyes of the human viewer;
- wherein the display is curved and is positioned to be in a line of sight of the human viewer when the human viewer is viewing the display;
- and
- wherein the optical subsystem includes
- a pair of curved quarter-wave plates disposed closer to an intended viewing location of the human viewer than the display, at least one of the curved quarter-wave plates being adjacent to the display;
- a curved, semi-reflective mirror disposed between the quarter-wave plates in the intended line of sight of the human viewer;
- a curved liquid crystal plate disposed on a surface of a one of the quarter-wave plates that is closest to the intended viewing location of the human viewer;
- and
- a curved polarization element disposed on a surface of the liquid crystal plate.

- wherein the optical subsystem comprises:
- preparation optics arranged to adjust a size or depth of the virtual image;
- and
- relay optics arranged to receive the light rays from the preparation optics and to relay the light rays to an exit pupil of the display system, wherein the preparation optics include a field-evolving (FE) cavity by which to modulate a trajectory of light ray bundles to modify a focal plane of the virtual image, and wherein the FE cavity is arranged to set different sections of the display to different depths.
