The detonation radiation spectra of TNT and Hassar explosives were measured and the radiation spectra were calculated to obtain the detonation temperature.The detonation radiation was collected with a fiber optic probe and the detonation was measured with an optical multichannel analyzer (OMA) The visible spectrum of the radiation was used to deal with the obtained spectral data mathematically, and the detonation temperature was obtained by fitting the Planck formula with the black body to the detonation spectrum according to the least squares principle.The density ρ was 1.4 84 g / cm3 and 1.570 g / cm3 The detonation temperatures of TNT explosives were 208.2 K and 208.6 K, respectively. The minimum mean square errors were 5.5 and 6.9, respectively. The density ρ was 1.72 g / cm3 and 1.84 g / cm3, respectively. Detonation temperature of 2916.4 K and 30 63.5K, respectively, the minimum mean square error of 5.4 and 5.3 respectively.TNT explosives detonation spectrum does not contain line spectrum components can be directly Planck formula fitted, and more High precision (small mean square error); Hassar explosives detonation spectrum contains spectral components, after smoothing and then fitting, get higher fitting accuracy
