The technique of power calibration of the THz continuous wave is a technique to calibrate the actual power of the THz source. In this paper, the principle of the technique of power calibration of the THz continuous wave is described, and a method of power calibration of the THz continuous wave is given, through the analyse of the characteristic of the technique of power calibration. The system of the power calibration of the THz continuous wave is implemented by the key element-the system of the heat-sensitive absolute power detection.In this paper, the principle of the system of the heat-sensitive absolute power detection is mainly studies, the indeterminacy of the power of the standard radiate sourcee is analysed, the theory evidence is provided for the study of the technique of power calibration of the THz continuous wave.
