A research team, led by RMIT University’s Distinguised Professor Min Gu, along with the Beijing Institute of Technology (BIT), has designed a nano-hologram that is easy to replicate, 1000x thinner than a human hair, and can be seen without the use of 3D goggles.
Gu goes on to say:
“Conventional computer-generated holograms are too big for electronic devices but our ultrathin 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.
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.
From medical diagnostics to education, data storage, defense and cyber security, 3D holography has the potential to transform a range of industries and this research brings that revolution one critical step closer.”
Dr Zengyi 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.”
A holographic 3D world, built within our smart devices, soon to be implemented all around us, is just around the corner.
