Abstract
A method for identifying the orientation of wood fibres (2) comprises the operating steps of generating at least one beam of light (4) polarised in a predetermined first polarisation plane, projecting the beam of light (4) onto a surface of a piece of wood (3) to illuminate a zone of said surface and generate diffuse light without polarisation and reflected light (5) polarised in a second polarisation plane (pX2), detecting the linearly polarised reflected light (5) and identifying the orientation of the illuminated fibres (2) at least indirectly based on the orientation in space of the second polarisation plane (pX2) of the reflected light (5). Also claimed is an apparatus (1) for implementing the method, comprising means for supporting a piece of wood (3), a light source (10) for generating at least one beam of light (4) polarised in a first polarisation plane (pS), a detection device (6) for detecting, in practice, the light coming from a zone of the piece of wood (3) illuminated by the beam of light (4) and for filtering said light based on its polarisation, and a processing device operatively connected at least to the detection device (6) for processing what is detected and identifying the orientation of the wood fibres (2) at the illuminated zone.
