German scientists from the Technical University of Munich have developed an imaging technology that uses Wi-Fi signals to construct 3D hologram images. This could be used to assist in search and rescue operations after disasters.

If you’ve played any of the recent Batman video games, you’re probably already familiar with his ability to scan through walls using one of the many gadgets he has at his disposal. In real life, German scientists from the Technical University of Munich (TUM) may have developed a technology that could give you a similar Batman-esque skill. What makes it even cooler? Basically all it takes is a Wi-Fi signal.
“It can basically scan a room with someone’s Wi-Fi transmission,” Philipp Holl said, speaking to Business Insider. Holl and TUM professor Friedemann Reinhard developed the concept behind the technology and published their findings in the journal Physical Review Letters.
It’s surprisingly simple, exploiting Wi-Fi’s ability to pass through walls. Using two antennas, they record a Wi-Fi field around a particular room. The antennas capture the intensity and the phase of the Wi-Fi field both from its source spot and the places it bounces off from. The result is a holographic image of the room that, while it’s not yet vivid, proves that the concept works in practice rather than just theory.
