I won’t let J be confused. Scientists have seen a way to fool thermal imagers

It would seem that the temperature changes to the infrared storage cannot be deceived. The fact is different: with the help of specially structured materials, scientists have been able to completely fit thermal imagers.

Thermal imagers display infrared from the surface of the body and the surrounding environment. Today, thermal imagers have a variety of uses, in both civilian and military applications, from home heat monitors to search engines, medical diagnostics, and aircraft and missiles. This is a new tool that has a number of problems. However, this does not mean that thermal imagers are infallible. Scientific darkness in various parts of the world is developing technology, with their help, thermal imagers and similar devices would be possible.

Zen of different wavelengths can be disturbed by our senses. For example, when we look at shiny surfaces, what we see is usually bad in the immediate vicinity of such an object and also in the current light conditions. The American University of California at Berkeley took on these optical illusions and devised a procedure for creating visual lures on the surface of selected objects. These lures can confuse infrared cameras and subsequently their operation, which detects the infrared image, but in fact it is not there.

Infrared or heat is invisible to the human eye. Nowadays, however, the whole device can detect it, from the glasses for non-vision and after changing the thermal camera. Junqiao Wu and his colleagues have developed a process whereby a special tungsten-doped vanadium oxide film can be applied to the surfaces. This film then emits the same infrared from the surface of the object as from the surrounding environment. Thanks to this, such a surface is practically invisible for thermal cameras and similar devices.

However, it is better that such special surfaces can be modified so that the thermal imager shows a false image. It creates an infrared signal of what is not actually there. As the creators of the material state, their surface films can still be manipulated and modified by infrared signals.

The first choice of vanadiite oxide was doped with tungsten. In such a material, a certain temperature is thus reached in the manner of the phase shift. The non-conductor, which suppresses the conductivity of the electric current, becomes at that moment a metal which, on the contrary, conducts an electric current over time.

Stl (but falen) temperature

The true structure of the material is to achieve that the surface with this material emits a constant infrared, which is stable over a wide range of ambient temperatures, from 15 to 70 degrees Celsius. In this way, it is possible to confuse the thermal imager and mask the real infrared signals that would otherwise emit the object at a given ambient temperature.

Similarly, the materials examined and gave the scientific science of darkness. Experts from the American University of Wisconsin at Madison worked with nickel oxide and samarium, while they tried to create a thermal mask from a mixture of germanium, antimony and tellurium at the University of Niangsk in Chang.

However, the team from Berkeley is convinced that he has made some significant progress. They were able to apply ultra-thin layers of vanadium oxide, which are less than 100 nanometers thick, on a substrate made of borosilicate glass and sapphire. Subsequently, they used laser pulses, with their help they doped vanadium oxide film with varying amounts of tungsten. Finally, the material thus formed was transferred to the site of the urn with a special adhesive tape made of polyethylene.

Wu and his colleagues claim that their method offers a better and more reliable camouflage. Their material is mechanically flexible, does not need an external source of energy and at the same time adapts to both fluctuating temperatures over time and temperature differences in space. By manipulating the bottom and composition of a tungsten-doped vanadium oxide film, the researcher created infrared lures, that is, infrared images of an object that does not actually exist.

The authors of the new material thus showed her in practice that it really works. They were able to create falen infraerven images of the letters C, A and L, ie the encounter of the word California, which they then placed on a selected surface. Each of these letters emits infrared corresponding to different surface temperatures. When someone uses an infrared camera on such a surface, they will find that the letter C corresponds to a constant temperature of 5 degrees Celsius, the letter A corresponds to a temperature of 15 degrees Celsius and the letter L to a temperature corresponding to 25 degrees Celsius. This is regardless of the actual temperature of the surface.

A team from the University of California at Berkeley was able to create a thermal camouflage. Their material emits infrared at wavelengths, which correspond to only one temperature. Thus, the surface temperature in each frame of the sinter, the thermal camera, the temperature of each letter is the same. The letter C emits a constant temperature of 5 degrees Celsius, the letter A a corresponding temperature of 15 degrees Celsius and the letter L for a temperature of 25 degrees Celsius.

Even if the actual temperature of the surface was between 35 and 65 degrees Celsius, when someone would observe the surface, for example with glasses for non-visibility, they would still see different cold letters C, A and L on them. As Wu points out, this is It is possible to delete real information about a given surface and, conversely, to create falsified information, which will confuse the observer.

Such technology must be worn by soldiers and reporters. Recently, there are still very advanced means for uplifting activity and it would certainly not be possible to have the possibility of such means. The use of this could be hidden some information, which is then searched only by someone who will be equipped with the necessary equipment.
