A team of researchers at at Germany’s Technical University of Munich have devised a method which uses WiFi signals to create a holographic radiation map. Using stray radiation from variety of devices like routers and phones, a 3D holographic image can be generated, presenting a mapped image of one's surroundings.
An undergraduate student who worked on the project describes the complicated process in simple terms. "Each device acts as a light bulb of different color and lights up its environment. Due to the longer wavelength of microwave radiation compared to the visible spectrum, the WiFi signals can pass through many materials, making walls appear transparent, almost like glass.”
2D images of WiFi radiation have been created, but the Technical University of Munich is the first to create a full three-dimensional image. Researchers say the device can be used to find anything from lost items, and can even aid in search and rescue missions.
