| description | A waveguide has an output diffractive optical element to couple light out of the waveguide towards a viewer, and a returning diffractive optical element to receive light from the output diffractive optical element and return the received light toward the output diffractive optical element. The output diffractive optical element has overlaid first and second output diffractive optical elements. The first output diffractive optical element receives light from an input direction and couples it toward the second output diffractive optical element in a first direction that is oblique to the input direction. The second output diffractive optical element receives light from the input direction and couples it towards the first output diffractive optical element in a second direction that is oblique to the input direction. The returning diffractive optical element has first and second returning diffractive optical elements that return light opposite the first and second directions, respectively. |
