Abstract:
Systems, devices, and methods for eyebox expansion in wearable heads-up displays (“WHUDs”) are described. The WHUDs described herein each include a projector and an optical waveguide positioned in an optical path between the projector and an eye of the user. For any given light signal from the projector, the optical waveguide receives the light signal at an input coupler and outputs multiple instances or copies of the light signal from multiple discrete, spatially-separated output couplers. The multiple instances or copies of the light signal may be converged by the optical waveguide directly to respective exit pupils at the user's eye or may be routed by the optical waveguide to a holographic combiner in the user's field of view from which the light signals may be converged to respective exit pupils at the user's eye. The optical waveguide employs exit pupil replication to expand the eyebox of the WHUD.

Claim (Index 10):
The optical waveguide of  claim 9  wherein the N output couplers are arranged in a single row across a length of the volume of optically transparent material, and wherein each of the N output couplers is at least partially reflective to couple a respective portion of light from the light source out of the volume of optically transparent material and direct the respective portion of light to a respective one of the N exit pupils, and each of at least N\u22121 of the output couplers is partially transmissive to transmit a respective portion of light from the light source through the volume of optically transparent material towards at least one other one of the N output couplers.
