Now a pioneering team led by RMIT University’s Distinguished Professor Min Gu has designed a nano-hologram that is simple to make, can be seen without 3D goggles and is 1000 times thinner than a human hair.
“Conventional computer-generated holograms are too big for electronic devices but our ultrathin hologram overcomes those size barriers,” Gu said.
“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.
“Integrating holography into everyday electronics would make screen size irrelevant – a pop-up 3D hologram can display a wealth of data that doesn’t neatly fit on a phone or watch.

Dr Zengji Yue, who co-authored the paper with BIT’s Gaolei Xue, said: “The next stage for this research will be developing a rigid thin film that could be laid onto an LCD screen to enable 3D holographic display.“This involves shrinking our nano-hologram’s pixel size, making it at least 10 times smaller.
“But beyond that, we are looking to create flexible and elastic thin films that could be used on a whole range of surfaces, opening up the horizons of holographic applications.”
