Holographic display ---Where the idea comes from? Guo Yu [1] Yu, Hyeonseung, KyeoReh Lee, Jongchan Park, and YongKeun Park. "Ultrahigh-definition dynamic 3D holographic display by active control of volume speckle fields." Nature Photonics (2017).

Behind the idea • Fundamental physics ideas.
Behind the idea • Scattering materials, like milk, turn light into a chaotic jumble. But if we could control how they scatter light, we could turn them into useful things like focusing devices.
