Abstract
The measurement of temperature and emissivity of objects is of significant importance in science, industry, and other areas. A lingering question regarding the validity of temperature and emissivity values determined using two-color ratio radiometric measure-ments has been answered. Although generally valid, certain spectral-band configurations can produce ambiguous results. General guidance in the selection of the spectral bands to maximize the sensitivity of the ratio with respect to temperature is presented. Several techniques to measure the emissivity of materials are discussed along with representative experimental results.
