and an interesting reference article Infrared thermography for convective heat transfer measurements http://link.springer.com/article/10.1007%2Fs00348-010-0912-2 That one's (at least partly) downloadable. It emphasizes that you have to take into account the wavelength-dependence of emissivity. (as in my http://lenr.qumbu.com/blackbody_141027A.php ) page 1189: However, since infrared camera detectors capture only a limited band of the whole electromagnetic spectrum, while making measurements with IR thermography, Planck’s law (2), rather than Stefan–Boltzmann’s law (4), has to be applied.
