Researchers from the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) at the Australian National University have developed a new all-optical approach to night vision technology. They have created an infrared filter thinner than cling wrap that could be integrated into everyday eyewear, allowing users to see both the infrared and visible light spectrum simultaneously. This advancement could lead to the widespread adoption of night vision technology in various applications, such as safer driving, night-time walks, and working in low-light conditions. The new technology, based on a non-local lithium niobate metasurface, eliminates the need for bulky cooling systems and heavy equipment traditionally associated with night vision devices. By using up-conversion technology, the system can capture both visible and non-visible images in one image, offering improved efficiency and resolution. The researchers aim to expand the device's sensitivity to different wavelengths and explore image processing capabilities for future applications in surveillance, navigation, and biological imaging industries. This breakthrough represents a significant step towards miniaturizing night vision technology and enhancing its practicality for everyday use.
