Abstract:
Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described. An optical device comprises an optical waveguide including a volume of optically transparent material having a first longitudinal surface positioned opposite a second longitudinal surface across a width of the volume, an in-coupler, a liquid crystal out-coupler, and a controller to modulate a refractive index of the liquid crystal out-coupler. Light is in-coupled into the waveguide and is propagated along a length of the waveguide by total internal reflection between the longitudinal surfaces before being out-coupled by the liquid crystal out-coupler on a path that is dependent on the modulated refractive index of the liquid crystal out-coupler. In this way, light signals can be steered to create an image and/or to move an exit pupil of an image. WHUDs that employ such optical waveguides are also described.

Claim (Index 3):
The optical device of  claim 1  wherein the liquid crystal out-coupler comprises at least two distinct, independently modulatable regions.
