<p>The invention relates to a method and arrangement for measuring the quality of wood. The wood comprises not only a pure body but also components of bark and knots, having optical properties different from those of the pure body. Barked trees (308) are turned into a wood powder (322). The wood powder (322) is illuminated with optical radiation and the radiation is received by means of a camera (330). The camera (330) transmits a signal consistent with the radiation refelected from or passed through the wood powder (322) to a computer (332) which, by means of the optical properties of the wood powder (322), determines the amount of bark, knots, and/or defective wood present in the wood.</p> |
