According to the British Daily Mail, a British company has recently developed a backpack machine that allows people to see through walls.
This wall-penetrating viewer is called "Prism 200c". It can penetrate solid objects and display things on the other side of the wall on a handheld screen. It is reported that this is the first time researchers have developed such a small device for personal carrying and use. The manufacturer, Cambridge Consultants, expects the wall-penetrating viewer to be used by law enforcement agencies or emergency services, especially suitable for soldiers to minimize errors in the shortest possible time under high-risk or hostile environments.
The wall-penetrating viewer can also penetrate wood, concrete or bricks, presenting any moving 3D images inside buildings. Users can stand on one side of the wall, use the device to scan with ultra-wideband radio waves, and then view the displayed items on the screen.
At the same time, the device can also be remotely connected to a computer or base commander to inform them of the conditions on the other side of the wall. Ultra-wideband radio waves are also known as pulse waves, which are difficult to detect and can work over a wide area.
