New System to Counter Photo and Video Devices
Incongruity writes "News.com is reporting that a team from Georgia Tech has developed and demoed a system that actively searches for and effectively blinds cameras and camcorders within a 10 meter radius." From the article: "In this system, a device bathes the region in front of it with infrared light. When an intense retroreflection indicates the presence of a digital camera lens, the device then fires a localized beam of light directly at that point. Thus, the picture gets washed out."

How it works
The Georgia Tech system essentially exploits the "retroreflective" property of digital camera lenses. When light strikes a retroreflective surface, a portion of the light bounces back to the original source. While eyeglasses, bottles, watches and other glass surfaces are retroreflective, a coating on virtually all digital camera lenses puts cameras in a class of their own.
