Abstract
An example device includes a screen, a first light source configured to emit a first light at a first angle during a first time period and a second light source configured to emit a second light at a second angle during a second time period. The second angle is different than the first angle. The second time period is different than the first time period. The device includes a spatial light modulator configured to provide a first view of digital content based on the first angle of the first light emitted during the first time period and a second view of the digital content based on the second angle of the second light emitted during the second time period and projection optics configured to project the first view and the second view for presentation via the screen.
Claims20
A device comprising:
- a spatial light modulator configured to:
- receive first light at a first angle during a first time period;
- provide a first view of digital content based on the first angle of the first light emitted during the first time period;
- receive second light at a second angle during a second time period, wherein the second angle is different than the first angle;
- and
- provide a second view of the digital content based on the second angle of the second light emitted during the second time period;
- and
- projection optics optically coupled to the spatial light modulator, the projection optics configured to project the first view of the digital content through a first sub-pupil of a pupil of a near-eye display and to project the second view of the digital content through a second sub-pupil of the pupil of the near-eye display.
A method comprising:
- receiving, by a spatial light modulator, first light at a first angle during a first time period;
- providing, by the spatial light modulator, a first view of digital content based on the first angle of the first light emitted during the first time period;
- receiving, by the spatial light modulator, second light at a second angle during a second time period, wherein the second angle is different than the first angle;
- providing, by the spatial light modulator, a second view of the digital content based on the second angle of the second light emitted during the second time period;
- projecting, by projection optics, the first view of the digital content through a first sub-pupil of a pupil;
- and
- projecting, by the projection optics, the second view of the digital content through a second sub-pupil of the pupil.
A near-eye display comprising:
- a first light source configured to emit first light during a first time period;
- a second light source configured to emit second light during a second time period
- a spatial light modulator optically coupled to the first light source and the second light source, the spatial light modulator configured to:
- receive the first light at a first angle during the first time period;
- provide a first view of digital content based on the first angle of the first light emitted during the first time period;
- receive the second light at a second angle during the second time period, wherein the second angle is different than the first angle;
- and
- provide a second view of the digital content based on the second angle of the second light emitted during the second time period;
- projection optics optically coupled to the spatial light modulator, the projection optics configured to project the first view of the digital content through a first sub-pupil of a pupil of the near-eye display and to project the second view of the digital content through a second sub-pupil of the pupil of the near-eye display;
- and
- a waveguide optically coupled to the projection optics.
