Original Abstract Submitted

a waveguide combiner assembly for an augmented reality or virtual reality display. a waveguide combiner has front and rear surfaces substantially parallel to a waveguide plane. a chassis includes a support arm for supporting the waveguide combiner and defining a cavity between front and rear walls of the support arm which are spaced along a first direction by a distance greater than the thickness of the waveguide combiner. a waveguide axis normal to the waveguide plane and the first direction define therebetween a zero or nonzero offset angle. an edge portion of the waveguide combiner extends into the cavity. at least one actively adjustable mounting structure is configured to hold a respective point of the edge portion of the waveguide combiner at a selected position relative to the support arm, thereby enabling adjustment of the offset angle.
