"light, 1 µm thick, ultra-flat metalens optic substantially extends camera battery life, but limited by chromatic aberration, overcome using AI-powered computation enabling 1 cm aperture... AI-powered backend takes in data received from optics/ outputs images with lower haze, better color accuracy, more vivid hues, better noise reduction... future: capturing/ working with polarized/ spectral sensing of light to augment human vision... nanoprint lithography metalens fabrication affordable/ scalable... ophthalmology devices"
