Paper Abstract

According to Kirchhoff and Planck's laws, it may be demonstrated that the measurement of the thermal radiation of a source, at n wavelengths, allows the determination of both its emissivity and its true temperature (T); the emissivity being described by an expansion in n-2 wavelengths. The accuracy of both thermal radiation and emissivity measurements, theoretically, grows with n for sources with purely thermal radiation.
