Abstract:
A display system includes a waveguide having a first diffractive optical element and a second diffractive optical element. The waveguide is configured to receive a display light having a pupil height and pupil width and transmit the display light to an eyebox with an eyebox height and an eyebox width. The first diffractive optical element is configured to in-couple the display light into the waveguide, the first diffractive optical element having a first diffractive optical element height that is at least the pupil height and a first diffractive optical element width that is at least the eyebox width.
