A New Method of Measurement of the True Temperature and Emissivity of Non-Black Body Using One Component of Wien’s Spectrum of Thermal Radiation

It is shown that the measurement of only one component of the Wein’s spectrum of thermal radiation in range λT ≤ 3000 (°;C μm) is sufficient to estimate the true temperature and spectral emissivity of the selected component with sufficient accuracy, although more than one hundred years this statement was considered as incorrect. The proposed method is based on the formation of the linear dependence of the logarithm of the emissivity of not real wavelengths and artificially generated “virtual” spectral components.
