Sci fi holographic images soon to be possible

A tiny holographic device is invented by physicists from The Australian National University.

Lead researcher Lei Wang said that the device can created complex holographic images in infrared..

“As a child, I learned about the concept of holographic imaging from the Star Wars movies. It’s really cool to be working on an invention that uses the principles of holography depicted in those movies,” said Mr Wang,  PhD student at the ANU.


can complete the most complex manipulations of light. They can store and reproduce any information from light in 3D. Compared to standard photographs and computer monitors that display only  2D information.

“While research in holography plays an important role in the development of futuristic displays and augmented reality devices, today we are working on many other applications such as ultra-thin and light-weight optical devices for cameras and satellites,” he said.

Mr Wang said that the device can replace many bulky and unwieldy components and save costs by reducing the weight and size.

The Co-author of the research Dr Sergey Kruk said the device was made of millions of small silicon pillars, that can reach in size to 500 times thinner than a human hair.

“This new material is transparent, which means it loses minimal energy from the light, and it also does complex manipulations with light,” said Dr Kruk from the ANU Research School of Physics and Engineering.

“Our ability to structure materials at the nanoscale allows the device to achieve new optical properties that go beyond the properties of natural materials. The holograms that we made demonstrate the strong potential of this technology to be used in a range of applications.”

The Australian National University leads the design and fabrication of the device.

The research was partly conducted with collaboration of Chinese and American researchers.
