Large-Aperture All-Solid-State Cascaded Liquid-Crystal Beam Steering for High-Resolution Wide-Field Imaging
Cascaded LC waveplates and Pancharatnam–Berry gratings steer sub-FOVs into one telephoto camera, yielding an 8.6× spatial-bandwidth-product gain over a same-sensor wide-FOV lens with >60% diffraction efficiency.
