Abstract: The present disclosure provides numerous applications for the use of liquid crystal polarization gratings (LCPGs) to controllably steer light. When combined with an image sensor, light generated or reflected from different fields of view (FOV) can be steered, allowing an increase in the FOV or the resolution of the image. Further, the LCPG can stabilize the resulting image, counteracting any movement of the image sensor. The combination of LCPGs and liquid crystal waveguides (LCWGs) allows fine deflection control of light (from the LCWG) over a wild field of view (from the LCPG). Further applications of LCPGs include object tracking and the production of depth images using multiple imaging units and independently steered LCPGs. The LCPG may be used in controlling both the projection and reception of light.

Abstract: A Liquid Crystal Waveguide (LCW) system can provide sub-aperture incoupling or outcoupling of light having an input wavelength and input beamsize defining an aperture characteristic of the system. A Liquid Crystal Waveguide (LCW) can include a generally planar LCW core to receive light via a light input zone for communication toward a light output zone. Sub-aperture interfacial light couplers can be planarly arranged in or parallel to the planar LCW core in the light input zone or the light output zone. Sub-aperture interfacial light couplers can include teeth, prisms, or facets, a photonic crystal metasurface, or a geometric-phased holograph (GPH)). Overall LCW thickness can be reduced, which can be helpful in space-limited applications or for reducing material costs.
