ABSTRACT: 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.
