Abstract:

A dynamic eyepiece for projecting an image to an eye of a viewer includes a waveguide layer having an input surface, an output surface opposing the input surface, and a periphery. The waveguide layer is configured to propagate light therein. The dynamic eyepiece also includes a mechanical structure coupled to at least a portion of the periphery of the waveguide layer. The mechanical structure is operable to apply a first mechanical force to the at least a portion of the periphery of the waveguide layer to impose a first surface profile on the output surface of the waveguide layer and apply a second mechanical force to the at least a portion of the periphery of the waveguide layer to impose a second surface profile different from the first surface profile on the output surface of the waveguide layer.
