PYROMETER MEASUREMENT IN PRESENCE OF STRONG AMBIENT RADIATION

摘要

Amethod is disclosed for measuring the temperature of remote hot samples (4) in the presence of ambient radiation (7). A portion of the surface of the sample (4) is for example treated (6), to obtain a spectral emissivity different from the untreated surface (5). The spectral radiances of the treated (6) and untreated (5) surface portions are measured and the temperature calculated from these values and the known emissivities.
