Silicon holograms harness the full visible spectrum to bring holographic projections one step closer. We can’t yet send holographic videos to Obi-Wan Kenobi on our droid, but researchers at A*STAR, Singapore, have got us a little bit closer by creating holograms from an array of silicon structures that work throughout the visible spectrum.
Many recent advances in hologram technology use reflected light to form an image; however the hologram made by Dong Zhaogang and Joel Yang from the A*STAR Institute of Materials Research and Engineering uses transmitted light...
