Abstract
A display may include a waveguide, projector that produces light, and an input coupler that couples the light into the waveguide. To maximize luminance uniformity, the display may include structures that perform one-dimensional pupil replication on the image light in a direction orthogonal to the direction of propagation. The structures may include a substrate stacked on the waveguide and having a pupil replication layer and light redirecting layer, may include crossed gratings that direct portions of the light to two pupil replication layers that are disposed within or on the waveguide, or may include an array of micromirrors in the projector that diffract illumination light in different diffractive modes to perform one-dimensional pupil replication.
