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.
