This study proposes a new thermal imaging system using the principle of two-color thermometry to determine the temperature of objects. The system can provide a thermal image of objects without being assigned their emissivity. Applying two-color thermometry to thermography is performed by dividing the detectable wavelength range of a radiation detector into two different ranges using respective band-pass filters. A thermal image is constructed from the two distributions of radiation energy which are measured after passing through each filter. In this study, in order to evaluate the accuracy of imaged temperature in the present system, an error analysis for imaged temperature are carried out and the accuracy in the present system is compared with those in a conventional thermography. This study also demonstrates the performance of the present system by imaging the temperature of objects with different emissivities and at different temperatures.
