CHARACTERIZATION OF ALGERIANS OAK WOOD BY X-RAY TOMOGRAPHIC SCANNER AND FREE SOFTWARE IMAGE-J

Abstract

The main objective of this work is the determination of the density variation in nine samples oak wood analysed at various depth thickness. The wood materials tested are taken from Yakouren forest situated in the north of Algeria, samples used for the evaluation were of oak Zeen and oak Afares trees, samples are preciously prepared by catting operation in the longitudinal and tangential direction. The analysis based on the absorption of X-rays generated by tomographic scanner, as the trails parameters could be appropriate in order to obtain a high resolution of images. After the images were analyzed by a specific free software image (Image J), this was done by reconstructing images taken on each depth scan in three different area of the samples, at the high, middle and low area. The results showed density distribution in all samples areas analyzed, even at different depth. the statistical investigation of results confirmed the anisotropy of the species wood analyzed, in addition the density distribution were strongly correlated in the three areas anlyzed with slight difference, and the evolution of density were noted as nonlinear in the two species oak studied.
