Corners in focus: Metasurface enables motion tracking without digital image processing
A research team at City University of Hong Kong (CityUHK) has developed a new optical corner-detection imaging method that uses azimuthal Hilbert transform metasurfaces and is designed to work as a universal framework. The study marks an important advance in high-speed, low-power optical information processing and has demonstrated potential for motion-tracking applications.
