‘flat optics’

Team demos breakthrough in analog image processing, Nature reports

Feb. 24, 2020—A research team of Vanderbilt engineers that includes a scientist at Oak Ridge National Laboratory has demonstrated a new ultrathin filter, based on metamaterials, that allows for analog optical image processing. Their work, Flat Optics for Image Differentiation, appears today in the scientific journal, Nature Photonics. While digital image processing has become the prevailing technique...
