Abstract

A new technique to improve the accuracy of the infrared radiation thermometry is presented. We combine the real time emissivity compensation with the three-colored technique proposed to suppress the effect of stray lights. We first examined the effectiveness of the three-colored technique and found that the measurement error caused by stray lights is decreased from 150 degree(s)C to 10 degree(s)C for the sample of 650 degree(s)C.
