Abstract
A near-eye display including a light source, an optical system, and a phase map including multiple pixels. The optical system is configured to receive illumination light from the light source and output the illumination light as an in-phase wavefront. Control logic of the near-eye display is coupled to variously program different phase patterns of the phase map at different times. The phase patterns are each to variously adjust phases of respective portions of the in-phase wavefront. For each of the phase patterns, the phase map is to form a different respective image in response to being illuminated by the in-phase wavefront.
Claims22
A near-to-eye display comprising:
- a light source to emit illumination light;
- an optical system configured to receive the illumination light from the light source and output the illumination light as an in-phase wavefront;
- a phase map including multiple pixels each positioned to receive a respective portion of the in-phase wavefront, wherein the multiple pixels are configured to collectively spatially modulate a phase of the in-phase wavefront;
- and
- control logic including circuitry coupled to the phase map to generate different phase patterns with the phase map by configuring a phase adjustment amount of the multiple pixels, each of the different phase patterns to form a respective image at a retina-distance from the phase map as the in-phase wavefront propagates through the phase map in response to being illuminated by the in-phase wavefront.
A system comprising:
- a smart contact lens comprising:
- a light source to emit illumination light;
- an optical system configured to receive the illumination light from the light source and output the illumination light as an in-phase wavefront;
- and
- a phase map including multiple pixels each positioned to receive a respective portion of the in-phase wavefront, wherein the multiple pixels are configured to collectively spatially modulate a phase of the in-phase wavefront;
- and
- control logic including circuitry coupled to the phase map to generate different phase patterns with the phase map by configuring a phase adjustment amount of the multiple pixels, each of the different phase patterns to form a respective image at a retina-distance from the phase map as the in-phase wavefront propagates through the phase map in response to being illuminated by the in-phase wavefront;
- and
- a base station communicatively coupled to the smart contact lens, wherein the base station is configured to wirelessly transmit communication data to the smart contact lens;
- and
- wherein each of the different phase patterns are generated by the control logic in response to the smart contact lens receiving the communication data from the base station.
