| Zusammenfassung | The laser-flash method is a fast, widely used and well established technique to measure the thermal diffusivity. Since its introduction in the 1960s it was proposed to expand this technique to the measurement of heat capacity and emissivity. Currently, the measurement of spectral emissivity at high-temperatures is connected with relatively large uncertainties, although the spectral emissivity is an essential parameter for applications, e.g. in lamp industry and fusion research. In the present work, a theoretical study is given on the possibility of emissivity measurement using the laser-flash method. Two mathematical approaches are discussed which solve the problem, that a measured temperature rise – necessary to calculate the emissivity – itself depends on the emissivity. It is shown that both methods have a negligible arithmetic error, making them applicable to be used in future work. |
