摘要：
A method of measuring the true temperature of bodies with unknown and variable emissive power during heating and cooling is considered. The method is based on the fact that the spectral emissive power depends on the temperature. The necessary number of spectral components is minimized by employing relative laser reflectometry, the use of which does not require that the radiating surface should obey Lambert's law. The results of measurements of the true temperature and spectral emissive Powers of specially manufactured high-melting point metals are presented. The overall error of a measurement of the true temperature does not exceed 1%.
