Abstract:
A method for measuring the quality of wood, in which method the wood is constituted by timber which, in addition to a pure body (100), includes at least a bark component (102) and knot components (106), which differ from the pure body (100) in terms of optical properties thereof, the method involving the barking of logs (202, 302), characterized in thatat least some of barked tree trunks (208, 308) are turned into a wood powder (212, 322); the wood powder (212, 322) is illuminated with optical radiation; and the quality of wood is measured by means of the optical radiation in such a way, that the wood powder is used for making a pixel-compiled real image thereof, and the wood powder has its quality determined by means of pixel-specific optical properties.
