Abstract
The system of optical control of the SH-Synthesis process based on high-speed camera "VideoSprint" (production of SPC "Videoscan", Russia) and the environment MATLAB. The purpose of the system is the determination of the velocity, size of the area, of the temperature of the synthesis reaction of the material. Developed a thermal imaging system with a frame size of 1280x1024 pixel, resolution of less than 6 microns per pixel, shooting speed of up to 50,000 frames per second and a temperature range of 1000 - 3500 K. The methods for automated analysis of data and evaluation of thermal macroparameters, depending on the stoichiometry of the boundary conditions and the heterogeneity of the charge . Results of testing of the control system in the identification of parameters of the SHS process depending on the density and the initial temperature of the charge stoichiometric NiAl.

Keywords: calibration, high-temperature synthesis, image processing and analysis, MATLAB, programming, self-propagating, SHS, speed, temperature, virtual instrument
