A signal processing method of mid-infrared multi-wavelength radiation thermometry based on wavelet transform is presented. Based on the different propagation property between signals and white noises under the wavelet transform, the white noise is eliminated from signals effectively with wavelet soft-threshold, and the signal processing for radiation thermometry is practiced expediently using software. In this paper, the method of wavelet transform introducing into radiation thermometry is discussed.
