The world's most imposing hologram will lead to the new 3D world

Interactive 3D holograms are the core of science fiction - from Star Wars to avatar - but it is challenging to change the originality of scientists, which develops adequate holograms to work with modern electronics. Under the guidance of RMIT University Professor Min Guy, a pioneering team has now created a nano-hologram that is common and can be seen without 3D glues and 1000 times thinner than a human hair. “Traditional computer-generated holograms are very large for electronic devices but our ultrathin hologram surpasses those size barriers,” Gu said.

“Our Nano hologram is ideal for large-scale applications and mass production using the usual and fast direct laser writing system. “Connecting the holography into everyday electronics incomplete screen size - A pop-up 3D hologram displays the wealth of data that is not properly matched on a phone or watch. "Education, data storage, protection and cyber security, 3D holography from Medical Diagnostics has the potential to change the range of industries and this research brings the revolution closer to a critical stage.

Traditional holograms modulate the light phase to give the illusion of three dimensional depths. But for adequate phase changes, those holograms should be at the thickness of optical wavelength. The RMIT research team working with the Beijing Institute of Technology (BIT) divides this thickness limit by a nanometer hologram based on a topological insulator material - a novel Quantum material with a lower refractive index in the surface layer, but refractive index in the ultrasonic group.

The topological film of the topological actuator acts as an internal optical resonant cavity, which improves stage changes for holographic imaging. "This will reduce my nano-hologram's pixel size, which is at least 10 times lower. “But beyond that, we see the opening of horoscopes of horizontal applications, creating comfortable and elegant narrative films that can be used in the entire range of surfaces.” The research was published on May 18 in the journal Nature Communications.
