American Football: Homeland Security Tries New 3-D Technology at Super Bowl XL

Hidden from public view at Super Bowl XL, live-action 3-D holograms created from signals streaming in from networks of electronic eyes will help Homeland Security Agency officials detect people and objects suspected of endangering the 65 thousand ticket holders crowding into Ford Field, and the thousands more celebrating in downtown Detroit.

While officials may not go public with the details, the surveillance effort is likely to include:

-- scanning undersides of vehicles for suspicious objects

-- face-in-the-crowd recognition and feature-matching

-- monitoring street-level festivities, day and night

-- underwater Detroit River monitoring

-- classified methods of searching for and detecting potential threats.
