Remote temperature sensing and thermal imaging systems [1, 2] are invaluable tools in various fields of science and technology. The fact that radiation is a function of object surface temperature makes it possible for remote temperature measurement systems to calculate this temperature. However, to measure temperature accurately with IR system, it is necessary to know emissivity. Emissivity is one of the major sources of error in radiometric measurements. Generally, emissivity is not constant as it depends on several parameters: temperature, viewing angle, wavelength, contamination or roughness. The article presents a laboratory heater which can be used to measure the thermal emissivity ε depending on the sample surface topography.
