Boffins have developed a system to create images of a room without seeing what is actually inside it.

The new technology works as Wi-Fi is not restricted to physical boundaries and has the capability to travel through objects.

While most of the Wi-Fi signals are received by the likes of our phones and computers, some signals remain in the open, which scientists have found a way to utilise.

The technology from German engineers sees two antennae put to use: one is stationary while the other is mobile.

The fixed antenna records the background of the Wi-Fi field while the other antenna is moved to different points to gain alternative reference points.

Both antennae record the intensity of the Wi-Fi signals and its ‘phase’ – the light property that comes from the wave.

Recordings are simultaneously fed into a computer which is then able to generate 3D holograms.
