Product description

High speed on-line grading system of wood by Vis-NIR spectroscopy.

We developed new high speed on-line grading system, which consists of NIR spectrophotometer and visible imaging camera.

The diffusely reflected spectra and imaging of woods were measured under running speed of conveyer at 120 m/min. Moisture content and Youngs modulus could be accurately predicted with aid of partial least squares analysis. Some defects (knots, crack, etc.) could be also detected using imaging analysis.
