NEW FACILITES OF RADIATION THERMOMETRY IN HEATING AND COOLING DYNAMIC

D. Y. Svet

Abstract

The new method of measurement of true temperature and emissivity is considered. The method is based on use of redundancy of the information of Plank's radiation and changes of properties of substance finding the reflection in change of emissivity factor from temperature. The simultaneous application of relative spectroreflectometry allows to reduce quantity of used spectral components and to determine emissivity's meanings, including surfaces, which are not following Lambert law. It is shown, that the method allows to build a thermodynamic temperature scale without using of black body.
