Physicists at Australian National University are developing a device that they claim would produce the highest quality of holographic images. Researchers used one of a kind silicon materials which may be the key to the success of this technology!

"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," Mr. Wang, a PhD student at the ANU Research School of Physics and Engineering told Phys
Holograms work using complex manipulations of light. These devices store and reproduce all information carried by light in 3D to create realistic images.
"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 added.
Researchers said that what they have created may replace bulky cameras that are even more costly. The newly improved hologram device may be used in astronomical missions, which are greatly reduced in size and weight compared to optical systems used in spacecrafts.
Co-lead researcher Dr Sergey Kruk said the key component of the hologram device are millions of tiny silicon pillars, which are 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," Dr Kruk from the ANU Research School of Physics and Engineering said in an interview.
"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."
