A vanadium dioxide metasurface lets the smart infrared sensor switch between edge-enhanced and full-detail views. Researchers from the City University of New York, the University of Rochester, the University of Melbourne, and RMIT University have created a compact sensor using image-processing metasurfaces. This sensor can be equipped on drones to provide cost-effective, large-scale monitoring of … Continue reading Smart Infrared Sensor With Crop-Monitoring Powers
