New Optical Screen May Slash Infrared Camera Costs
Researchers at the University of Melbourne have developed a metasurface screen that converts invisible infrared light into visible light. This innovation could significantly reduce the cost and complexity of infrared cameras by eliminating the need for expensive semiconductor detectors.
Why it matters
Lowering the cost of infrared technology could democratize access to advanced imaging for industrial, medical, and security applications.
New research led by the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) at the University of Melbourne demonstrates a new way to make invisible infrared light visible without relying on the expensive detector technology used in today's infrared cameras.
Infrared is a type of light our eyes can't see, while carrying information about heat and objects in the environment. It's widely used for environmental monitoring, industrial inspection, medicine and security.
However, technology such as infrared cameras remain expensive because they rely on specialised detectors that are costly to manufacture and often require cooling.
The international team of researchers demonstrated a new way to see infrared light that could one day make these systems smaller, lighter and far less expensive.
