Caption: Researcher Dan Becker demonstrates NIST's prototype imaging system for remote detection of hidden weapons. The inset on the left is the image created by the instrument, which detects naturally emitted or reflected light at sub-millimeter wavelengths. The ceramic knife is cooler and reflects cooler light from the room, and therefore appears darker than the surrounding image.
