The choice of a car in the secondary market is full of surprises, and you can buy a broken car with a painted body. Sometimes damage is difficult to identify with the naked eye. The novelty scanner is capable of detecting the smallest damage to the body, but it is not yet clear how it can compare favorably with the tools already existing on the market. Let’s figure it out.

The Shvabe holding, which is part of the Rostec state corporation, presented a unique device for checking hidden damage to a car. The scanner is able to detect the smallest damage to the body, even if they have been repaired in the most meticulous way. The device has already received a patent and is being prepared for release at two enterprises — NPO Orion and Research Institute Polyus.

The message that RIA Novosti received from Rostec says that the device works on the principle of impulse action on the surface of the body. Thus, «the inhomogeneity of the thermal fields is revealed,» which ensures the localization of hidden damage to the metal. The main components are two cameras, a backlight, a signal converter (probably referring to an analog-to-digital converter, ADC) and a data analysis unit. It is also reported about a computer that will interpret all the information received. It is not yet clear whether this means an integrated processor or the analysis will be carried out on an external PC. Judging by the general description, it can be assumed that the scanner is based on the principle of microwave radiation (as in a microwave oven), due to which the inhomogeneity of heating is revealed.

Oleg Yevtushenko, executive director of Rostec, claims that there are no analogues of such a device in the world today. And the state corporation itself has high hopes for the innovative device. It is assumed that the unique development will become an indispensable aid in the work of car services, field diagnostics, agents of insurance companies, autocriminalists and other services dealing with autoexamination.

It only remains to add that one always wants to be happy about domestic innovations, but a number of questions inevitably arise. The most important of them: how does the new product compare favorably with the classic automotive paintwork thickness gauge? Today, several basic types of these devices are known, including both primitive mechanical and rare industrial ones — for example, for measuring the thickness of a layer on magnetic surfaces. But for many years in the everyday life of any Trade-In salon or the arsenal of an insurance auto appraiser there is a compact and accurate electromagnetic measuring device for paintwork thickness.

It is almost impossible to deceive this device even with the most careful approach to coating repair — it is unrealistic to apply coating layers on the repaired metal surface just like from a factory. And due to the fact that over the years the choice of thickness gauges on the market has become simply immense, even an expensive ultra-precise gauge will cost 30 thousand. For the organization’s budget, this is what is called “dust”. In addition, these «electronic evaluators» are getting smaller in size and higher in accuracy. So how will the new device from Rostec be able to attract potential operators? So far, this is a very big question.
