The main purpose of the simulation model was to determine the rational parameters of measurement and control of the informationmeasuring system developed by the authors, which would simplify the process of setting up such a system, as well as explore the dynamic modes of its operation. The main advantage of the developed simulation model is the ability to conduct an interactive study of the operation of the information-measuring system under various, including limiting, modes. Tests of the simulation model of the information-measuring system made it possible to study its operation under various conditions and modes of the measurement experiment, as well as to virtually determine the rational operating parameters of su...

The aim of the work is to determine the optimal regimes of electron-beam microprocessing of dielectric materials by studying the volt-ampere characteristics of the wire Pierce electron-beam gun. In the methodical part of the scientific work, a technological experiment with electron-beam microprocessing of dielectric surfaces is proposed, and also identified and studied the operating modes of the Pierce electron-beam gun in depending on their energy characteristics. As a result, the analysis of the obtained results of electron-beam microprocessing of surfaces of dielectric materials makes it possible to increase the reproducibility of the results of such treatment in terms of purity and residual nanorelief by 18-25 %. The comparison of the results of experimental electron-beam microprocessing of dielectrics with the results of their laser processing made it possible to establish a decrease in the residual microroughness of the surface of the optical glass K8 by 17...27 times with electron-beam microprocessing and by 12-14 times with surface laser treatment. Wherein, surface laser processing does not allow to eliminate the undulation of the surface, which is related to the specificity of the interaction of the laser beam with the surface of the optical material, whereas, when processing by the ribbon-shaped electronic stream such undulation does not appear. Conclusions and analyzed data obtained in the article based on the results of experimental studies can be used to optimize the technological regimes of electron-beam microprocessing in the production of micro-optics products, integrated optics, microelectrooptics, nanoelectronics, etc.

As a result of the experiments, it was found that the spatial resolution of the improved thermographic method (compared to the standard method of determination) was improved by 15 – 20%, and the spectral resolution by 0.3 – 0.5 μm. According to the results of the analysis of the processed image, the adjusted temperature scale of the thermogram, which, in turn, allowed to increase the accuracy of temperature determination in each accurate image (the temperature distribution error did not exceed 5.5%).
