Near-to-eye display with steerable phased arrays
Near-to-eye devices with steerable phased arrays are provided. In some configurations, a device comprises waveguides, e.g., color plates, that are individually formed to couple a corresponding color output of a micro-display engine and project an image into a human vision system. Some configurations include steerable phased arrays for generating light defining a field of view of image content. The generated light is aligned with light from a real-world view to create an output that concurrently displays the real-world view with the field of view of the image content. The light from the steerable phased arrays is directed through one or more waveguides to an output region of the one or more waveguides. The light from the real-world view can pass through transparent portions of waveguides in a manner that aligns a rendering of the image content with the light from the real-world view to create augmented reality views.
1. An optical device, comprising:
a controller modulating one or more output signals comprising image data defining image content;
a first steerable phased array generating a first light of a first predetermined wavelength range, the first light forming a first field of view of the image content based on the one or more output signals;
a first waveguide having a first input region for receiving the first light and a first output region, the first waveguide reflecting the first light within the first waveguide towards the first output region;
a second steerable phased array generating a second light of a second predetermined wavelength range, the second light forming a second field of view of the image content based on the one or more output signals;
a second waveguide having a second input region for receiving the second light and a second output region, the second waveguide reflecting the second light within the second waveguide towards the second output region;
a third steerable phased array generating a third light of a third predetermined wavelength range, the third light forming a third field of view of the image content based on the one or more output signals; and
a third waveguide having a third input region for receiving the third light and a third output region, the third waveguide reflecting the third light within the third waveguide towards the third output region, wherein the first output region, the second output region, and the third output region are aligned with a lens directing light from a real-world view to create an output concurrently displaying the real-world view with a composite field of view of the first field of view, the second field of view, and the third field of view.
2. The optical device of claim 1 , wherein the first output region, the second output region, the third output region, and the lens are aligned to project a rendered object in a predetermined position relative to a view of a real-world object.
3. The optical device of claim 1 , wherein the light from the real-world view passes through transparent sections of the first waveguide, the second waveguide, and the third waveguide.
4. The optical device of claim 1 , wherein the first predetermined wavelength range comprises a first range including 460 nm, a second range including 525 nm, or a third range including 617 nm.
5. The optical device of claim 1 , wherein the second predetermined wavelength range comprises a first range including 460 nm, a second range including 525 nm, or a third range including 617 nm.
6. The optical device of claim 1 , wherein the third predetermined wavelength range comprises a first range including 460 nm, a second range including 525 nm, or a third range including 617 nm.
