China continues to progress without technology brakes. Although many innovations focus on the civil sphere, others reinforce their military and intelligence power. Proof of this is an experimental system that promises to analyze objects kilometers away. We are talking about a technology that could promote an important leap in its espionage capabilities.
The information comes from South China Morning Post, which details how a team from the Aerospace Information Research Institute of the Chinese Academy of Sciences has achieved successful observations with an innovative laser system. This operates in optical wavelengths and helps obtain huge distance images, if certain conditions are met.
A new observation system
As we can see in the visual representation, the researchers displayed the system on a shore of the Qinghai lake, an immense Alpine lake in the remote northwest of China. On the other side, to 101.8 km awayThey installed a set of reflective rhymes. The impressive thing is that, despite the huge distance, the system managed to distinguish details of just 1.7 mm wide.
The laser makes the difference. They say that it reaches an accuracy of 15.6 mm when measuring distances, which theoretically leaves the spy and telescope chambers with lenses, surpassing them by a factor of 100. Now, the observations must be made with optimal climatic conditions, stable wind, low cloudiness and, in observations of the orbit, clear skies.
Although the tests have been performed on land, the Hongkonés newspaper points out that this technology could be used for espionage from space. Its unprecedented capacity to capture details would allow Identify faces from orbit Or, in reverse, analyze satellites from adversary countries with great precision from the surface of our planet.
If the question is how they have achieved it, the answer is in a combination of innovations. To begin with, the researchers divided the laser beam into a 4×4 microlent matrix, which allowed to expand the optical opening of the 7.2 mm system (0.68 inches) to 68.8 mm (2.71 inches). With this approach, they managed to overcome the usual limitation between the size of the opening and the field of vision.
In addition, they incorporated a specialized laser module capable of emitting signals with frequencies higher than 10 gigahecks. Thanks to this, the system reached an extremely fine range resolution, allowing distance measurements with great precision. At the same time, a narrow spectrum was maintained to improve the azimuth resolution, thus optimizing detail detection.
