"dual-mode imaging metalens transitions between normal and edge modes based on direction of light polarization rotation fine-tunes size, shape, and rotational orientation... focus by adjusting voltage applied to liquid crystal layer, allowing for rapid mode-switching in milliseconds... hydrogenated amorphous silicon lens efficiency 32.3%, 31.7%, and 20.4% for red, green, and blue...swiftly capture high-resolution images (bio-imaging, cellular reactions, drug screening), smartphones, VR and AR, and fixed LiDAR"
