Title (EN) METHOD FOR IDENTIFYING PROPERTIES OF WOOD BY INFRA-RED OR VISIBLE LIGHT
(FR) PROCEDE SERVANT A IDENTIFIER LES PROPRIETES DU BOIS PAR INFRAROUGES OU LUMIERE VISIBLE
Abstract:
(EN) A method for assessing logs before primary processing, or wood pieces before subsequent processing, in order to predict the behaviour of wood during subsequent processing, or to predict one or more wood characteristics which are important for end use, such as susceptibility to internal checking during drying, likelihood of dimensional instability, and elastic modulus, comprises subjecting logs or wood pieces to a source of infra-red radiation, detecting the levels of reflected radiation over the infra-red range or at a number of wavelengths in the infra-red range, and analysing the infra-red reflectance spectra relative to stored comparative information on infra-red reflectance data for logs or wood pieces.
(FR) Procédé servant à contrôler des rondins de bois avant leur premier traitement ou des pièces de bois avant leur traitement ultérieur, de manière à prédire le comportement du bois pendant un traitement ultérieur ou à prédire une ou plusieurs caractéristiques d'importance en vue d'une utilisation finale, telles que la susceptibilité d'une gerce intérieure pendant le séchage ou d'une instabilité dimensionnelle, et son module d'élasticité, ce qui consiste à soumettre les rondins ou les pièces de bois à une source de rayonnement infrarouge, à détecter les niveaux de rayonnement réfléchi dans la totalité de la plage des infrarouges ou à plusieurs longueurs d'ondes dans la plage des infrarouges et à analyser les spectres de réflectance infrarouge par rapport à des informations comparatives mémorisées concernant des données de réflectance infrarouge de rondins ou de pièces de bois.
