Pyrometry by means of the intrinsic emission of substances with a varying emissivity
Abstract
A relationship between the emissivity and the thermal emission wavelength is used as the basis for determining the true temperatures of substances with unknown and varying emissivity. The relationship permits the determination of emissivity, independently of temperature, by a polynomial approximation procedure. Identification and measuring techniques are analyzed, and individual cases are considered.
