Abstract:
An apparatus having optical waveguides for providing a large FOV is disclosed. A first light engine projects light into an input diffractive coupler of a first waveguide at a first central angle. An output coupler of the first waveguide projects the light out of the first optical waveguide. A second light engine projects light into an input diffractive coupler of a second waveguide at a second central angle that is greater than the first central angle. An output coupler of the second waveguide projects the light out of the second optical waveguide to intersect with the light projected out of the first optical waveguide. The first waveguide may be used to project a first part of an image into a central portion of a user's vision. The second waveguide may be used to project a second part of the image into a peripheral portion of the user's vision.
