Abstract:
In a method for determining the dry mechanical strength for a green wood, the improvement comprising:(a) illuminating a surface of the wood to be determined with a reduced range of wavelengths in the VIS-NIR spectra, said wood having a green moisture content; (b) analyzing the surface of said wood using a spectrometric method, the method generating a first spectral data of a reduced range of wavelengths in VIS-NIR spectra; and (c) using a multivariate analysis to predict the mechanical strength of green wood when dry by comparing said first spectral data with a calibration model, said calibration model comprising a second spectrometric method of spectral data of a reduced range of wavelengths in VIS-NIR spectra obtained from a reference wood having a green moisture content, the second spectral data being correlated with a known mechanical strength analytical result obtained from said reference wood when dried and having a dry moisture content.
