At the Scientific Research Center of the Russian Academy of Sciences, the technology of acousto-optic filtration of optical radiation is used to create a wide class of optical devices that are successfully used, for example, in biomedicine to diagnose various diseases (including oncology), in agriculture to diagnose the condition of plants, during non-destructive testing of complex technical objects and in solving other tasks. Acousto-optics has a number of important advantages over other technologies for obtaining spectral information: - the ability to create imaging devices without spatial scanning, since the acousto-optic filter is a software-controlled tunable light filter; - the compact modular design allows the acousto-optic filter to be integrated into the optical circuit of most imaging devices, which expands their analytical capabilities; - spectrum scanning is carried out by means of an electrical signal, without mechanical scanning; - fast arbitrary spectral addressing causes high shooting speed and the absence of redundant information; - software management. The key element of the presented device – an acousto–optic filter - is being developed at the Scientific Research Center of the UP RAS on the basis of original calculation methods. The manufacture of acousto-optic filters, optical and mechanical components, as well as the assembly, tuning, and calibration of such devices is also carried out at the Scientific Research Center of the UP RAS.

The principle of operation of the electroplating thickness gauge: A converter with an induction coil on a ferrite core generates a high-frequency signal (frequency 1 MHz), which is used to create an alternating magnetic field. As the converter approaches the conductive surface, an alternating magnetic field creates eddy currents, the magnitude of which depends on the characteristics of the metal base and the thickness of the coating. In turn, eddy currents create their own electromagnetic field, which can be received by an induction coil. The resulting signal enters the amplitude detector, after which it is transmitted to the processing unit, where it is digitized and displayed on the device readout. In addition to signal conversion, the processor is used to set the required gain, as well as the initial voltage offset, depending on the characteristics of the materials in the controlled object. Features of the device design and advantages of the measurement method The TL-1MP eddy current thickness gauge consists of an electronic unit with a display, a power supply and a converter. The device is controlled using four buttons located on the front panel of the electronic unit. The converter can be disconnected from the electronic unit during transportation or for convenience of storage. The advantages of the device include: - convenience and ease of operation; - small size and light weight, allowing the TL-1MP to be used in difficult conditions with limited access to the controlled area of the facility; - high measurement accuracy; - factory setting of the measuring instrument to the customer's requirements; - high degree of localization of defects due to the small size of the converter. Scope of application: The service life of metal parts and components of mechanisms used in mechanical engineering is largely determined by their resistance to corrosion and surface wear. However, not all metals are sufficiently resistant to external destructive influences. Therefore, various electroplating coatings made of zinc, nickel, chromium, cadmium, tin, copper, silver and other metals are used to protect them. Even small fluctuations in the thickness of protective coatings can significantly affect the performance characteristics of parts, their service life, and interaction with other components. Therefore, measuring the thickness of the metal coating applied by the electrochemical method is important when conducting quality control of products. The use of the TL-1MP eddy current thickness gauge allows non-destructive quality control of electroplating coatings on the surface of metal parts in mass production conditions with special requirements for product quality. The device detects even small mechanical defects, the effects of abrasion, erosion, corrosion on the surface. Due to its ease of use, efficiency and reliability, eddy current thickness measurement is a standard method of quality control of products with electroplated coatings in such industries as mechanical engineering, aerospace industry.
