Abstract

The invention teaches a method for measuring the temperature of remote hot samples in the presence of ambient radiation. A portion of the surface of the sample is treated to obtain a spectral emissivity different from the untreated surface. The spectral radiances of the treated and untreated surface portions are measured and the temperature calculated from these values and the known emissivities.
