FIELD: determination of temperature of moving objects-particles. SUBSTANCE: radiation intensity is measured at decomposition into spectrum. Spectral intensities are summed up during measurement on N wave lengths from flying unequally heated particles of condensed phase observed when heterogeneous object moves in lateral direction relative to preset section. Then total thermal spectrum U is obtained from unequally heated particles. This spectrum is vector of the following values: u(l<SB>1</SB>), u(l<SB>2</SB>)...u(l<SB>i</SB>)...u(l<SB>N</SB>), where u(l<SB>i</SB>) is total spectral intensity obtained on wave length l<SB>i</SB>. This done, histogram Z of temperature distribution of particles is determined. It represents vector of values Z(T<SB>1</SB>), Z(T<SB>2</SB>),...Z(T<SB>N</SB>) at N preset temperature in compliance with the following formula: <EMI ID=0.212 HE=6 WI=18 TI=CHI> (1), where A is size N.N matrix of values {a(l<SB>i</SB>, T<SB>j</SB>)} of spectral intensity of black body radiation determined by Planck radiation formula on each of measured N wave lengths and at each of N preset temperatures. Average temperature of particles is found from formula <EMI ID=0.213 HE=12 WI=66 TI=CHI>. EFFECT: higher measurement results. 1 dwgi
