Researchers have created 3D holograms using graphene
Scientists at Swinburne University of Technology in Melbourne, Australia have developed the real deal, 3D holograms that do not require the use of 3D glasses.
By bending light through a graphene oxide lense, they are able to make it seem like the light is coming from a seperate display, creating a full-color, pop-up, 3D floating image which can be viewed from a wide angle, (52 degrees) a huge step up from the few degrees of visibility in previous holograms.
According to Min Gu, one of the authors of the design, "we can create the wide angle display necessary for mobile phones and tablets."
Here is an image, released by the team, of one hologram that has been produced
The researchers have only created holograms up to 1 centimeter off the display but say that it will be very easy to scale that up. In their paper, they write "it is projected that graphene 3D display at tens of centimetre scale, perfect for the wearable displaying devices, will be available within five years. This new generation floating 3D display technology also has potential applications for military devices, entertainment, remote education and medical diagnosis."
Also noted by the team is that it doesn't involve any heating or change in temperature, but relies on a rapidly pulsing laser beam to change the way the light bends, making it much more user friendly and scalable.
I'm excited for when we can project, via video chat, into someone's room at full scale hologram size
