A team of physicists from Edinburgh promise an imminent revolution in the security field and not only. At the center of their project there is a device able to analyze a vehicle or a particular subject also at a kilometer away.
The technology employed is called the “time of flight” and it has already been adopted for the systems “driverless cars”, but there were problems in perceiving the most distant objects. And the precision at long distance is just the characteristic of pride of the new product that exalts the probabilty of error at most an millimeter.
Let’s see how it works: the object that you want to investigate is hit by an infrared laser beam at low-voltage and according to the “time of flight”, so to the lightspeed of return (in addition to an image processing software), it makes a very accurate reconstruction.
The creators hope to develop a range of action of 10 km, if they will obtain the permission to proceed, and clearly also the necessary funding. Always the scanner designers believe that, thanks to future corrections on the image processor, it will possible to measure the speed and the direction of an object. The tool will certainly have uses in the military field, in areas of war or to prevent the risk of terrorism.
There is still a limit in the use of the scanner: it doesn’t detect the human skin because it reacts differently once it has hit by a laser, compared to other materials, leaving an image unclear. So to keep under control at long-distance humans and their movements will we have to make use of GSM bugs, tools that allow you to listen from any distance and that, through powerful software, also offer the possibility of eliminating any external noise. In short, the field of security and surveillance no longer knows boundaries of both time and space.
