A pair of German researchers have developed a method to harness Wi-Fi signals to capture 3D hologram images of objects around a network, even through solid barriers like doors and walls.

“All pixel inputs are contributing to the holographic image in all planes, which gives us more light efficiency as well as better spatial resolution in the final 3D object, as the projected ...

If you've seen "Star Wars," chances are you've seen the futuristic hologram projectors that create three-dimensional images in the air ... sends the laser through a 3D scanner, which reflects ...
