Abstract

In the research of multi-spectral radiation thermometry, temperature measurement depends on the line shape of spectrum radiation remittance. However, in the actual measurement, the combustion, explosion and gasification on special occasions can produce some particulate matters which can create the phenomena of scatterings such as Mie scattering, Rayleigh scattering and Debyd scattering. These phenomena will affect the linear of spectral line directly. The particulate matters can also make the object’s line shape of spectrum radiation remittance changed through the transmission of scattering medium. Therefore, it will affect the precision of temperature measurement. Based on the theory of blackbody radiation, this thesis researches on not only the influence and revision of multi-spectral radiation thermometry by Mie scattering, but also the influence and revision of solar temperature measurement by the phenomenon of PM2.5 scattering. The thermal error will drop from 20% to 10% through the revision. The research will improve the precision of temperature measurement.
