Gas transport in wood assessed by laser spectroscopy

In English The Gas in scattering media absorption spectroscopy (GASMAS) technique provides new opportunities to nondestructively study gas in highly scattering natural and man-made porous materials. In this paper, we report applications of the GASMAS method on wood samples using diode-laser-based spectroscopy on molecular oxygen. And the integrated oxygen absorption for wood of different densities and the anisotropy related to the fibre structure was also investigated
