Abstract：In recent years, with the rapid development of cutting-edge technology at domestic and foreign, temperature measurement has a very important guiding significance and research value in the field of national defense construction and industrial manufacturing. Especially in the transient ultrahigh temperature measurement, temperature measurement accuracy requirements are more stringent. Because of its high precision and applicability, multi spectral method is widely used by experts at domestic and foreign. In this paper, a new method is proposed to solve the transient excitation temperature and radiation temperature of the target with high accuracy at the same time. This method can obtain the target excitation temperature by finding the higher reliability of the target physical characteristic data and the more accurate multi spectral line fitting method. By establishing a more accurate mathematical model and algorithm, the effect of spectral emissivity on the whole process of temperature measurement is reduced. The relevant temperature measurement experiments show that the system temperature measurement accuracy of this method reached 3%.
