Holograms Help Protect Super Bowl
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.
Looking at the rather skimpy article, it doesnt appear to be a hologram, any more then the special effects were in the movie it references.
holograms *require* interferrence patterns.. i dont see that happening with this product.

I am a holographic engineer.
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.
"When an event is designated a National Special Security Event, the Secret Service assumes its mandated role as the lead agency for the design and implementation of the operational security plan."

I'm guessing the parent an example of Guerilla Marketing. The when the Penny Arcade guys expounded that the marketers hung out in various popular forums, I instantly thought there might be some on /.
Sure it does. Says so in the 3rd paragraph.
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.
A quick search on google for "lifevision3d" comes up with http://www.intrepiddefense.com./ There's even a picture: http://www.intrepiddefense.com/index_files/Page392 .html
Of course the picture doesn't show anything interesting except a box labled "Patent Pending U.S. Government Security Prototype"
The funniest thing is the url. Page392.html? Come on...don't tell me with all the money they're spending on this they have someone making a site in Microsoft Publisher. *view source* wow...

The only good thing about the Super Bowl is the commercials.
And you can download them from this site, too.
