Reduction of methodological errors in determining the temperature of metals by two-color pyrometers
Tóm tắt
Two-color methods of optical control of the thermodynamic temperature of metals subjected to thermal treatment are analyzed. A technique for taking into account the nonmonochromaticity of the photoreception path is suggested and an analysis of methodological errors of two-color pyrometers with wide spectral ranges is performed by numerical simulation.
