This new invention by the German scientist can now make it possible to see through walls, they have found a way to take 3D holograms of objects from different views.
It was discovered by two students from the Technical University of Munich; Friedemann Reinhard and his colleague Philip Holl.
We are all aware of the power of Wi-Fi as it can pass through different walls to help us browse the internet in some range.
Their method uses Wifi signals to scan through a room. Using two antennas, they register a Wi-Fi field circling a particular room. Well, these two antennas are used to obtain the phase and intensity of the field, both from source spot and areas it bounces off.
According to them, this method will be very useful in the case of any disaster such as after earthquake or collapse of buildings as it can enable you to see from the other end through walls.
Concerning privacy issues about this new invention, Friedemann Reinhard said in a press release “It is rather unlikely that this process will be used for the view into foreign bedrooms in the near future. For that, you would need to go around the building with a large antenna, which would hardly go unnoticed.”
