TWO-COLOR COMPENSATIVE THERMOMETRY WITH CORRECTED ADJUSTMENT USING NONLINEARITY EQUATION OF EMISSIVITY SPECTRAL DISTRIBUTION
The article is directed on metrological characteristics increase and extension of the optical thermometry field of use, including two-color compensative thermometry with a priori averaged adjustment. The investigations have been performed for the tungsten. This metal studied in thermometry and metal optics has tabulated quantitative estimations of emissivity which are similar to the most widespread in metallurgy iron-carbon alloys.
