- Abstract:
- The paper deals with the method of on line radiation measurement of the true temperature and emissivity in the process of heating or cooling. The method may be realized without any precalibration. The realization of the method is based on simultaneous measurement of the intensities of self-radiation and of directional reflected radiation on two wavelengths for three values of temperature. The method involves the use of relative directional reflectometry which does not require the validity of the Lambert law for radiating surface. For the method to be realized in practice, the accuracy of radiometric and reflectometric measurements must be significantly increased.
