Abstract
A waveguide includes a waveguide body including an optically transmissive material having a refractive index different from a surrounding medium and defining an output surface. The waveguide body is configured to propagate light by total internal reflection in one or more directions substantially tangential to the output surface. The waveguide includes one or more diffractive optical elements (DOEs), each configured to change its diffraction efficiency in response to a respective stimulus, and a DOE driver configured to provide the stimuli to each of the DOEs independently.
