Technical University of Denmark in Roskilde researchers are developing a device that can convert mid-infrared radiation into visible light. Attached to a digital camera fitted with an infrared flash, it could detect tumors by recording the telltale pattern of infrared light they reflect.
The device could be placed in front of a digital camera lens like a filter, and be used to take thermal photographs or video.Current mid-infrared color imagers need to run at -200°C and cost around $100,000; an upconversion imager would run at room temperature and cost about $10,000.
