Abstract  The emissivity measurement method based on controlling surroundings radiation is presented. By using two plate with different temperature to realize controlling the surroundings radiation, reflectivity is obtained by measuring the variation of reflected radiation, then the emissivity is got through the relationship between reflectivity and emissivity. The theory of the measuring principle and the experimental device are discussed. Ultra black paint emissivity were measured by this method, the emissivity results and uncertainty of the results are presented. The relationship between the emissivity difference of the paint and the surface property is studied by scanning electron microscopy.
