Your smartphone could soon project holograms, letting you play games and browse things like Maps in amazing 3D!

A team of researchers from Australia’s RMIT University and the Beijing Institute of Technology has been able to clone some Ironman-like tech…

To understand why this is amazing, we first need to know a little about how holograms work…

A hologram is made using lasers because all the light waves are the same size and bend the same way.

To create a hologram, one laser beam is divided into two identical beams with the help of a special lens. When the two laser beams meet, they create what is called an interference pattern. That’s recorded on to film to create the 3D illusion!

Current hologram technology is somewhat limiting because the film has to have the same thickness as the light’s wavelength. As a result, it is too thick to incorporate into phones.

However, scientists have managed to create a hologram film 1,000 times thinner than a single strand of human hair! This means you can add it to a phone and holograms can be observed from different angles without special goggles…
