The article presents the results of increasing the accuracy of the operating parameters of the electron flow (power density, speed of electron-beam processing) in obtaining optical plates of small thickness as components of optical instrumentation devices. It is shown that flexible control of such parameters of tape electron flow allows to significantly (1.5-2 times) increase the accuracy and quality of surface processing of small thickness (up to millimeters) optical silicate plates (glass K8) by low-energy electron flow. The implementation of such management was carried out using an information-measuring system, the general principles and functional scheme of which are given in this article. The proposed system allows with high accuracy (relative error does not exceed 4.5%) and efficiency (the time between the moment of
determining the parameters of the electron flow to the moment of its formation with the adjusted values of these parameters does not exceed 12-17 μs).

The article develops a simulation model (based on the MatLab Simulink mathematical processor) of an information-measuring system of electrical characteristics (residual surface electric charge, surface layer capacity, etc.) of functional coatings of electronic devices. 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 such a measurement and control system. A satisfactory discrepancy of 8-11,5% was established for the experimental results compared with the data obtained analytically, which proves the correctness and adequacy of the compiled model.

The article presents the results of the development of an information-measuring system for monitoring the sanitary status of tree stands. The main purpose of such a system is to minimize the impact of the operator on the results of monitoring the sanitary status of tree stands by indirectly controlling the quality characteristics of the tree sap (by establishing the dependence of these characteristics on climatic factors) with the possibility of remote monitoring and control of the process of express control. The developed monitoring system allows to conduct a contactless (remote) survey of sensors, which are recorded in close proximity to the root system of selective trees from an array of tree plantations, and further, by mathematical treatment of climatic characteristics (acidity and salinity index, air temperature) zoning temperature health status. The system also allows you to predict the dynamics of extending the areas of tree planting. This enables those responsible for tree planting to take preventative measures to prevent such droughts. The main advantage of the developed information measurement system is its complete computerization, which eliminates a number of external subjective influences by the operator or the responsible person (necessity of visual inspection of the maximum number of trees in the array, erroneous perception of visual information, etc.). This, in turn, avoids systematic methodological errors, thereby improving the accuracy, speed and reliability of the monitoring and control results of this system.
