Abstract

In this study, we start from WIEN´s approximation to define and derive Alpha difference spectrum, which is independent of temperature. Then, we present a correction term to remove the influence of WIEN´s approximation on Alpha difference spectrum. On these bases, a new temperature and emissivity separation algorithm is advanced, which combines attractive features of Alpha derived emissivity method and ASTER TES algorithm. Compared with current TES algorithm, the new algorithm is fast, simple and precise. It can be used for wide temperature and surface type ranges
