WAVEGUIDE OPTICS FOCUS ELEMENTS
First Claim
1. An imaging structure, comprising:
- a waveguide configured for viewing of an environment that is viewable with the imaging structure, the waveguide further configured to transmit light of a virtual image that is generated to appear as part of the environment; and
one or more focus elements integrated in the waveguide and switchable to focus the virtual image at a focus depth that approximately correlates to a focal distance of the environment.

Abstract
In embodiments of waveguide optics focus elements, an imaging structure includes a waveguide for viewing of an environment that is viewable with the imaging structure. The waveguide transmits light of a virtual image that is generated to appear as part of the environment for augmented-reality imaging or virtual-reality imaging. The imaging structure also includes one or more focus elements that are integrated in the waveguide and switchable to focus the virtual image at a focus depth that approximately correlates to a focal distance of the environment. The focus elements can each be implemented for a different focus depth of the virtual image, and the focus depth is adjustable based on a combination of the focus elements being switched-on or switched-off.
