How would you like to have x-ray vision like the "Man of Steel"? Well, researchers at the University of Texas have designed an "imager" chip that could let you see through walls, wood, or plastic with just your cell phone! The research team made use of the tetrhertz, a band on the electromagnetic spectrum which was previously inaccessible for most consumer devices.

Dr. O and his team are focused on uses in the distance range of less than four inches, but as technology grows who could imagine the uses. It could be used a s a stud-finder in walls, to authenticate important documents, or detecting counterfeit money. It could turn you into Superman, seeing through walls!
