"Michelangelo's David Successfully Recognized by Compact Facial-Recognition System"

Scientists have developed a new compact facial recognition system that uses flatter, simpler optics and requires less energy than existing 3D imaging systems in smartphones. The system, tested on a replica of Michelangelo's David, employs metasurfaces and a photonic crystal surface-emitting laser to generate customizable and versatile light patterns, making it more energy-efficient and suitable for integration into a single chip. The new system recognized the face as well as existing smartphone facial recognition while using 5-10 times less power.
