Abstract
A method of operating a dynamic eyepiece in an augmented reality headset includes producing first virtual content associated with a first depth plane, coupling the first virtual content into the dynamic eyepiece, and projecting the first virtual content through one or more waveguide layers of the dynamic eyepiece to an eye of a viewer. The one or more waveguide layers are characterized by a first surface profile. The method also includes modifying the one or more waveguide layers to be characterized by a second surface profile different from the first surface profile, producing second virtual content associated with a second depth plane, coupling the second virtual content into the dynamic eyepiece, and projecting the second virtual content through the one or more waveguide layers of the dynamic eyepiece to the eye of the viewer.
