Temperature measurement of heated bodies with monotonous spectral distribution of emissitivity

Method of increasing reliability of temperature measurement via spectrum measurement is described. The approach to temperature measurement, developed in MPEI, based on ratio pyrometry statistic processing, in some cases leads to sufficient results, when emissitivity is unknown. But when emissitivity has monotonous spectral distribution mentioned above method leads to big uncertainty of a measurement.

Keywords: pyrometry, thermodynamic temperature, heated body radiation spectra, statistic processing, emissitivity.
