Quasicrystal metasurface projects holographic images and light patterns simultaneously - EurekAlert
Scientists created a new metasurface that projects holograms and unique light patterns. This ultrathin material combines quasicrystals (ordered but not repeating structures) with light manipulation techniques. They achieved this dual function by arranging tiny structures and controlling light interaction. This paves the way for ultra-thin devices in holographic displays, anti-counterfeiting, 3D imaging, and even multi-substance detection tech.
