The Homeland Security Department is aiming to arm federal agents with a light-saber -type weapon that emits a dazzling strobe capable of subduing criminals, terrorists and even unruly airline passengers.
The device works by temporarily blinding and disorienting a person, says Bob Lieberman, president of Intelligent Optical. Once aimed at someone's eyes, a series of light pulses and colors can be triggered and the subject's eyes can't adjust quickly enough to see.
"It's like someone shooting off a flashbulb in your face every few seconds," Lieberman says. "Because of the wavelengths and frequencies we use, there are psychophysical effects - a real disorientation. The reaction can range through vertigo to nausea."
That's why The Register, an irreverent online publication that covers the information technology industry, dubbed it the "puke-ray."
