A system used for dynamic calibration of transient surface temperature transducer is studied. For a heat source which is heated up to high temperature by a pulse laser, the dynamic response of temperature sensor is calibrated in the system by means of comparison of the result measured by a temperature sensor to be calibrated with that measured simultaneously by an infrared detector. In this paper, the principle of laser application to the dynamic calibration system for transient surface temperature transducer, composition of the system and experiment results are given. The experiment data show that using pulse laser as an exciting source in the system is feasible.
