Characterization of Oven-dry Oak Wood (Quercus robur L.) Emissivity in LWIR Spectral Waveband

This research paper reports on oven-dry oak wood (Quercus robur L.) emissivity value. Emissivity is very important property of material and it is used in infrared (IR) thermography. IR thermography is a non-destructive testing (NDT) method for measuring the temperature distribution of an observed object surface. It is applicable in a wide range of industrial and science applications. Currently in literature available emissivity values for wood differ from one another, and there is insufficient important complementary data. Often temperature, IR spectral waveband, wood specie, texture and other relevant wood information are not specified. Therefore the experiment for establishing oven-dry oak wood emissivity values within spectral range 7.5 – 13 μm (LWIR) was conducted, and the obtained results are presented in this research paper. Determined oak wood emissivity along with all important supporting data will facilitate the application of infrared thermography in wood related processes.
