Abstract:
Correlated color temperature, which describes the chromaticity characteristics of a radiating source, is different from its thermodynamic temperature derived from primary spectrum pyrometry. However, establishing their mathematical relationship is feasible. Therefore, the authors theoretically analyzed the variation rule of the correlativity difference between the correlated color temperature of the source and its thermodynamic temperature with the emissivity parameter. And the authors gave the corresponding numerical simulation results. The above theoretical and numerical discussions will make it possible that a colorimeter used to measure the correlated color temperature serves as a pyrometer to realize the measurement of the thermodynamic temperature.

Correlation
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
