Researchers at the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) have recently achieved a groundbreaking advancement in night vision technology.
They have developed an ultra-thin infrared filter, thinner than a piece of cling wrap, that could be integrated into everyday eyewear.
Traditional night vision devices are often bulky and heavy, limiting their use to specific professions like the military and wildlife photography.
However, this new filter, weighing less than a gram, could be incorporated into regular glasses, allowing users to see both visible and infrared light simultaneously.
The technology behind this breakthrough lies in a non-local lithium niobate metasurface, which enhances infrared vision through a process called non-linear upconversion.
Unlike traditional night vision that requires bulky cooling systems, this metasurface operates at room temperature, further reducing the size and weight of the device.
