Applying discoveries in quantum mechanics, researchers can now do ultrasensitive thermal imaging at room temperatures. The advance expands what infrared detectors can sense. The U.S. Defense Advanced Research Projects Agency is now providing Virginia Tech funding to increase sensing capabilities through the work of a research team that includes Yu Yao, an associate professor in the School of Electrical, Computer and Energy Engineering, part of the Fulton Schools, whose expertise includes optoelectronic devices. The project aims to enhance infrared detectors so they can monitor body temperature, spot forest fires, track rockets, missiles and airplanes, and possibly do early disease detection.
