Brand new ultra-thin material was recently developed that somehow manages to trick the human eye into perceiving really highly detailed images in 3D. The good part is that this time, you won’t need special glasses!
For the people that get excited when it comes to science fiction, 3D hologram is instantly recognizable genre. There are many examples – just think of Tony Stark’s virtual displays in the movie Iron Man or let’s say, Princess Leia fromr2-d2 in Star Wars.
But, for optical engineers – the true freestanding hologram for the last few decades is literary the Holy Grail. Maybe you remember the virtual Tupac. This was just one of the many small scale prototypes that engineers have developed over the years. Now it’s time for a progression!
Australian and Chinese scientists recently have worked on one material that show be the world thinnest hologram. Even if this material is hundreds of times smaller than a human hair, somehow is manipulating the light on the nano scale and the result of this is producing 3D holographic effect, that can be applied of course – to most of the electronic displays that we have today.
Nature communication published the paper – so if you’re interested in the terms and condition, check the link here.
Just for the records, these images are not freestanding in it’s literal sense. The technology just found a way to trick the eye with manipulating light that works similar like the symbol on your credit card.

“You can see the holographic image at a certain angle range and you don’t have to look directly at the screen,” Gu said in an email. “If the pixel size of the hologram is smaller, the view angle of the reconstructed image will be larger.”
“The hologram is recorded in our material point-by-point using a direct laser writing system,” Gu said. “Each of the points generates a phase shift that leads to the hologram effect.”
Gu said there is no telling when the nano-hologram technology will actually be incorporated into consumer devices.
“This depends on many factors, like solving technical problems and industry investment,” Gu said.
As to our abiding dream of Princess Leia holograms, Gu was unequivocal: “Freestanding images could be created like those in science fiction films.”
