Holograms Help Protect Super Bowl 287
Apache4857 writes to tell us CNet is reporting that Homeland Security agents monitoring the Superbowl will be doing so in 3D. Using streams from two cameras, the LifeVision 3D system is able to project images onto a 20-inch screen that is equipped with a depth tube. This depth tube makes images appear to rise 30 inches off the screen and sink 30 inches into the screen allowing real world volumes and distances to be displayed accurately. Using this system security officials will be able to search sidewalks, monitor faces, and even peer under vehicles.

holograms *require* interferrence patterns.. i dont see that happening with this product.

This is not a hologram because it is not creating an interference pattern. No phase information is stored.
To make a real hologram, you do need a monochromatic light source. Before lasers they used various lamps (mercury lamp etc) that illuminate at specific wavelengths. This does kinda work, but has a very short coherence length so is bad for making analogue holograms (a hologram of an actual object). Quite possibly a lamp could be used for copying holograms or for digital holography.

It's a load of balony, of course. You can't peer under a car unless one of the cameras is, you know, peering under the car. Or you're using some crazy x-ray emitting cameras that will leave everyone in the parking lot sterile.
Sounds to me like either the CEO of this company doesn't even know what his product is capable of, or CNET is just making up crap.
