A waveguide combiner with dynamic grating activation is described herein. In an example, an apparatus includes a first optical element that is configured to receive light. The apparatus also includes a substrate configured to propagate the light received by the first optical element along a propagation path within the substrate. The substrate includes an input surface and an output surface. The input surface is coupled to the first optical element. The apparatus also includes a second optical element coupled to the output surface and configured to output the light propagated along the propagation path. The second optical element includes a plurality of diffraction gratings at the output surface. Each one of the plurality of diffraction gratings has a corresponding controllable diffraction efficiency.

Waveguide combiner with dynamic grating activation

Techniques for an optical lens set and optical combiner are described herein. In an example, an apparatus has a first side and a second side. The apparatus includes an optical combiner and a first optical lens disposed at the first side. The image combiner is configured to output light emitted by a light projector as a virtual image projection within a field of view. At least a first portion of the first optical lens is within the field of view and is characterized by a first optical power that provides a first optical correction. The first optical power compensates for a second optical power of a second optical lens optionally disposable at the second side.
