(Phys.org)—By carefully arranging many nanoblocks to form pixels on a metasurface, researchers have demonstrated that they can manipulate incoming visible light in just the right way to create a color "meta-hologram." The new method of creating holograms has an order of magnitude higher reconstruction efficiency than similar color meta-holograms, and has applications for various types of 3D color holographic displays and achromatic planar lenses.
