Soon Tupac will be performing in your living room.
In work published in Nature Communications (Open Access) last week, scientists from Swinburne University of Technology have reported the use of graphene oxide and laser physics to create a pop-up 3D image, which could be applied to your smartphone or tablet. the method works through a photonic process, highly dependent on the refractive index (the measure of how light bends through a material) of the graphene oxide. By carefully tweaking the refractive index, they were able to make nanoscale pixels of reduced graphene oxide (rGO).
In a press release, Professor Min Gu said, “If you can change the refractive index you can create lots of optical effects.Our technique can be leveraged to achieve compact and versatile optical components for controlling light. We can create the wide angle display necessary for mobile phones and tablets.”
He thinks this new technology has applications in military devices, entertainment, remote education and medical diagnosis- a bold claim, but is it a good one? Let us know in the comments.
