Scientists have created the world’s thinnest hologram that can be seen without 3D goggles and may be integrated into everyday electronics such as smartphones, computers and TVs.

Interactive 3D holograms are a staple of science fiction but the challenge for scientists trying to turn them into reality is developing holograms that are thin enough to work with modern electronics.

Now, researchers led by RMIT University in Australia have designed a nano-hologram that is simple to make, can be seen without 3D goggles and is 1,000 times thinner than a human hair.

“Conventional computer-generated holograms are too big for electronic devices but our ultrathin hologram overcomes those size barriers,” said Min Gu, Professor at RMIT. The nano-hologram is fabricated using a simple laser writing system, which makes the design suitable for large-scale use 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 does not neatly fit on a phone or watch. The RMIT team worked with the Beijing Institute of Technology in China on the project.
