Abstract

Abstract

This study aimed to analyze the spectral response in ten commercial wood veneers from ten forest species, in the visible and near-infrared regions of the electromagnetic spectrum. Reflectance of samples was obtained using a Field Spec®3 spectroradiometer. Results were verified through the analysis of variance followed by a Tukey range test on multiple means, which showed significant differences in both the analyzed spectral regions for the studied species. The most expressive differences were observed in the visible region and occurred between the “tauari” and “nogueira” wood veneers. Those results may be due to the chemical properties of the analyzed material, to the cellulose content, to the proportion of the components in the cell wall and to the extractives in the lumen, to microfibril angle, density and to resistance and stiffness properties. Therefore, the applied technique was a tool capable to identify reflectance variations in regions of the electromagnetic spectrum which correspond to peculiar colorimetric characteristics of each species.

Keywords: Spectroscopy; reflectance, spectral signature, wood veneers.
