FIELD: measurement equipment.
SUBSTANCE: invention relates to pyrometry. In method radiation is collected and focused, three spectral ranges are identified, radiation is converted in each i spectral range into electric signal, which is amplified and processed. Length of wave of the beginning of the second spectral range matches length of wave of the end in the first one, and the third spectral range is the sum of the first and second spectral ranges.
EFFECT: provision of possibility to remotely measure temperature of objects surface with unknown coefficient of radiation, which provides for valid and accurate measurement of temperature without availability of information on coefficient of radiation of investigated surface.
