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.
