New nanocrystals could allow for night vision technology to be applied to a conventional pair of glasses.
Researchers at ANU used an array of nanoparticles, just 500 times smaller than a human hair, to create what’s called a metamaterial with superior capabilities.
The nanocrystals when powered, can convert photons of infrared light into visible light.
The nano crystals are so small they could be fitted as an ultra-thin film to normal eye glasses to enable night vision.
Professor Dragomir Neshev from ANU said the new night-vision glasses could replace the cumbersome and bulky night-vision binoculars currently in use. He said:
“The nano crystals are so small they could be fitted as an ultra-thin film to normal eye glasses to enable night vision.
This tiny device could have other exciting uses including in anti-counterfeit devices in bank notes, imaging cells for medical applications and holograms.”
Ultra-thin nano crystal film developed at ANU.
Co-researcher Dr Mohsen Rahmani said the ANU team’s achievement was a big milestone in the field of nanophotonics, which involves the study of behaviour of light and interaction of objects with light at the nano-scale. He said:
“These semi-conductor nano-crystals can transfer the highest intensity of light and engineer complex light beams that could be used with a laser to project a holographic image in modern displays.”
