Hots N. Scientific and technical principles of metrological assurance for infrared radiation thermometry

The thesis is devoted to the development of metrological assurance for infrared radiation thermometry. A methodology for system development of metrological assurance system for radiation thermometry is proposed. The method of the temperature scale realization to thermometers of infrared radiation according to the Planck radiation law is developed. For its realization, the model of temperature scale transmission is formed, and the method of constructing of interpolation equations as well as the method of providing linear calibration function of infrared radiation thermometer are developed. The expediency of introducing multiband methods for measuring the temperature of infrared radiation thermometer is justified, generalized models of the thermodynamic temperature by different methods are formed. Criteria of spectral channels of multi-channel radiation thermometer are elaborated. The mathematical relationship between the error of radiation temperature measurement and relation signal/noise ratio of the detector are formed. Recommendations are elaborated concerning the improvement of the regulatory assurance for radiation thermometry and the formation of modern terminology of this measurement type. The method to process the results of calibration of radiation thermometer based on uncertainty estimation, and the methodology assessment for its linear calibration function are formed. A national standard project for methods calibration of reference transducer is developed.
