FIELD: measurement equipment.
SUBSTANCE: invention is related to technology of temperature measurement. In method intensity of spectral lines of plasma flux radiation is measured twice, at first intensity of spectral lines is measured in radiation of flux without particles of condensed phase, and then in total heat and linear spectrum of two-phase plasma flux, from which then all values are excluded on those lengths of waves, where intensity of spectral lines of plasma is not equal to zero. According columns and rows are excluded from matrix of spectral intensity values produced in compliance with Planck radiation formula.
EFFECT: improved accuracy of detection of temperature distribution of condensed phase particles in two-phase plasma flux.
