Comparison of Methods for Estimating Mechanical Properties of Wood by NIR Spectroscopy

Figure 4

Relationship between lab-measured wood properties and NIR-fitted wood properties, (a) density, (b) modulus of elasticity (MOE), and (c) modulus of rupture (MOR). The broken line represents the line of equivalence. 332 samples were used to develop the density calibration, while 334 samples were used to develop the calibrations for MOE and MOR.
