AB - The infrared temperature measurement technique has been applied in various  fields with the development of Charge Coupled Device (CCD). In the problem of  metal surface temperature measurement, if the surface is covered by  participating media, the traditional infrared temperature measurement  technique will lead to intolerable measurement errors. In this work, the  infrared temperature measurement problem was solved by the Source Multi-Flux  method. On this base, the impact of the flue gas thickness and surface  temperature on the apparent temperature measured by the CCD was analyzed.  Furthermore, the corresponding experimental system was set up. And the  experimental results were found to have a good agreement with the simulated  results. Finally, the idea of modification for the infrared temperature  measurement by inverse method was proposed.
