Abstract
A pyrometer includes a light source capable of emitting light to at least two wavelengths to a target to be measured. A light measuring member measures the light source and provides output signals representative of those two wavelengths. A second light measuring member measures light reflected by the target and provides second signals corresponding to the two wavelengths. A third light measuring member measures the intensity of the light radiated by the target with respect to those two wavelengths to produce third signals. An emissivity is assumed for the target based on the predetermined wavelengths, and a temperature is calculated on the basis of the minimum value of the difference between the assumed radiation intensity calculated according to the assumed emissivity of the target and the measured radiation intensity in accordance with the third signals.
