Researchers Create Thinnest Hologram in the World

Computer-generated holography has actually been around for decades, but it's a technology whose use has been relegated to specialized fields such as optical microscopy and metrology. Thanks to 3D technology, however, we may soon be using holograms in everyday life, with no special equipment needed other than a smartphone. A team of researchers led by RMIT University Distinguished Professor Min Gu has designed a nano-hologram that can be seen without 3D goggles and is 1,000 times thinner than a human hair. According to RMIT, it's the thinnest hologram ever created. Read more at 3DPrint.com: http://3dprint.com/175426/thin-hologram-rmit-beijing/

Well, we're already using holograms in everyday life; on credit cards, novelty items and even on some banknotes. What advantage extreme thinness confers I'm not sure.
