The Predator is probably a creature that made many folks interested in infrared cameras and now researchers at Northwestern University have come up with a new infrared imaging system that offers a 16-fold increase in resolution over long wavelength infrared radiation (LWIR) cameras currently used in industrial, security and nighttime surveillance applications. This is achieved thanks to a semiconductor called a Type-II InAs/GaSb superlattice, and the IR camera is mercury-free, more robust, cheaper to produce and can collect 78 percent of the light showing temperature differences as small as 0.02 degrees Celsius.
