"ANTI-TERROR: Infrared camera enlisted to battle bioterrorism"
A compact, powerful way to perform infrared spectroscopy could speed the quest for ubiquitous organic sensors to head off bioterrorist attacks. In 10 milliseconds, the shoe-box sized planar-array infrared (PA-IR) spectrograph identifies airborne chemical and biological weapons by deriving a unique "signature." By contrast, today's methods, using laboratory-scale Fourier Transform IR (FT-IR) spectrographs, can take up to 30 minutes.
