FIELD: measurement technology. ^ SUBSTANCE: method is base upon separation of spectral components of radiation for three or more wavelengths. After spectral components are separated, radiated is subject additionally to polarization filtering by means of polarization-sensitive system which has at least four photoreceivers for each spectral component of radiation. Degree of polarization of metal self-radiation and degree of radiation polarization from zone of processing are taken into account. Spectral distribution of radiation is calculated. Averaged value of color temperature of metal is calculated from three values of temperature of metal by using methods of statistical processing. ^ EFFECT: improved precision of measurement. ^ 1 dwg |
