FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and a method of measuring actual temperature and spectral emissivity of an object. Method consists in that, in a given spectral range, the object is alternately sighted by two single-type optical radiation receivers and their output signals are measured. Desired parameters are calculated from measured signals. Radiation coefficients of the receivers are selected so that the emissivity of one of the receivers is close to or equal to one, and the emissivity of the other is substantially less than one. Receivers are preliminary graduated by model of absolutely black body.
EFFECT: technical result is increase in the measurements accuracy.
