Researchers develop ultra-compact camera with the size of a salt grain Researchers from Princeton University and the University of Washington have developed an imaging system that is the size of a coarse grain of salt. It is built on a so-called metasurface with 1.6 million cylindrical posts and can work exactly like a camera sensor.Continue reading “Researchers develop ultra-compact camera with the size of a salt grain”
