Abstract

A radiometric method for resolving the emissivity, /spl epsiv/, and temperature, T, in thermal emission measurements is derived and experimentally demonstrated. The viewed source´s own emission is utilized as an incoherent probe beam by means of a beamsplitter and return mirror. Measurements of several refractory materials at 137 GHz to 1500/spl deg/C were carried out.
