Abstract: A CCD IR thermography system can be used to measure the model surface tempe~ratures up to 3500K.In this paper,the system calibration test and dynamical compare test are introduced.The surface temperatures distribution of the hemispherical and small blunt model in high enthalpy facility are measured by the CCD IR thermography system. The results are compared with that obtained by an infrared pyrometer.It indicats that the developed system is successful and it will play an important role in high enthalpy wind tunnel experiment.
