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.
Forschung und Lehre
Remodeled bandsaw and circular saw to control washboarding during sawing:
The purpose of our study is to control the rugged sawn surface like washboard during ...
We introduced tim-of-flight spectroscopy to clarify the optical characteristics of wood. The device mainly consist of semiconductor laser and streak camera.
