RMIT’s answer was to create the world’s thinnest hologram…and they’ve done it. They’ve got the size down to 1,000 times thinner than a human hair.
Professor Min Gu:
“Computer-generated holograms are too big for electronic devices but our ultra-thin hologram overcomes those size barriers. Our nano-hologram is also fabricated using a simple and fast direct laser writing system, which makes our design suitable for large-scale uses and mass manufacture.”
