Physical and technical aspects of radiometric thermometry from the standpoint of a new definition of the temperature unit

We consider the physical and technical aspects of the transition to a new definition of the temperature unit as a physical quantity, reveal the features of the implementation of an absolute method for its reproduction in radiometric thermometry, and outline the physical foundations of the method and its theoretical substantiation. A comprehensive analysis of the procedure for reproducing the temperature unit according to its new definition is given, features of the implementation of the method in reference radiometric thermometry are shown, and an estimate of the measurement error is given.
