High-tech front in the war on terror From David Ensor WASHINGTON (CNN) -- While United States soldiers press on with their mission in Afghanistan and domestic security agencies try to flush out potential attackers, the war on terror is also being fought on another, more subtle front: in the laboratory. New technology -- some of it still under development -- has the potential to increase the effectiveness of intelligence-gathering efforts. For instance, officials at the Salt Lake City Olympic Games used 3-D maps to help plot their security strategy -- determining where to put observation posts and which facilities were most vulnerable to a terrorist attack, from which angles. And although black-and-white images are useful, and color images even more so, they still have drawbacks. Neither kind of image can reveal camouflaged facilities like a command post or bunker. Experts say a new technique called hyperspectral imaging can do just that. The devices measure the energy emitted or reflected from an object in more detail than can be provided by a conventional camera or thermal imager. "With hyperspectral imaging you're looking at literally hundreds of different colors, and minute differences in those colors can tell you the difference between leaves and a camouflaged command post," says John Pike, director of GlobalSecurity.org, an Alexandria, Virginia-based group that analyzes security risks and weapons improvement. Hyperspectral imagery can also be used to detect heat sources -- such as a campfire in a cave, or heat escaping from an underground vent -- and even trace chemicals in the air that might be escaping from a clandestine weapons factory.
