Now researchers at Swinburne University of Technology have shown the capacity of a technique using graphene oxide and complex laser physics to create a pop-up floating display without the need for 3D glasses.

Graphene is a two dimensional carbon material with extraordinary electronic and optical properties that offers a new material platform for next-generation nanophototonic devices.

Through a photonic process without involving heat or a change in temperature, the researchers were able to create nanoscale pixels of refractive index  the measure of the bending of light as it passes through a medium  of reduced graphene oxide. This is crucial for the subsequent recording of the individual pixels for holograms and hence naked eye 3D viewing.
