Researchers shrink high-res color camera down to the size of a grain of salt

Researchers from Princeton University and the University of Washington have developed a high-resolution color camera roughly the size of a coarse grain of salt. This new sensor technology combines meta surface optics and machine learning models to reconstruct images via the nano-optic imager. Specifically, the research paper detailing the technology says 'Nano-optic imagers that modulate light at sub-wavelength scales could enable new applications in diverse domains ranging from robotics to medi...
