CNN - "During the Cold War, Canada's National Optics Institute developed a system to detect which type of enemy tank or fighter jet was approaching. After the Soviet Union's demise, such threats were deemed less likely, and the technology sat on the shelf. Until 2003, when entrepreneur Eric Bergeron toured the institute with September 11 on his mind. "The flash I had was that we no longer look for Russian planes in the sky, but we do look for bad things in luggage," Bergeron said. The X-ray analysis company that emerged, Quebec-based Optosecurity Inc., is only on the verge of putting its devices in real-life checkpoints. But its hopes are emblematic of the massive homeland security technology industry spawned by September 11."
