Drones with X-Ray vision

Kind of… 

X-Ray vision was still thought to be a thing of the future…

…we are now in the future. Researchers are trialling a process that uses WiFi signals and a little interpolation to literally see through walls.

The system is two-fold, one drone blasts WiFi through the structure and another picks up the signal.

They then work in tandem, the two drones fly around the solid structure until it maps the differences in wave strength at different points. Using this information the researchers have been able to create a 3D model of a closed building.

Although you won’t be able to see though walls in incredible detail, the process has implications to be used in emergency situations when you need to know what’s inside the building without breaking down the doors.
