[PDF][PDF] Optimization of nondestructive quality control of wood panels by using refracto-vibrometry
T Marhenke, J Hasener, J Twiefel - … & EHW, 14.–18.07. 2013: 10th …, 2013 - researchgate.net
The manufacturers of wood based panels test the quality of these boards since more than 30
years with nondestructive ultrasonic devices. To optimize this technique in consideration of
the maximum board thickness and of the minimum density of wood based panels, the
refracto-vibrometry is a useful device. It is a reactionless method for the visualization of
ultrasonic waves and based on the laser-vibrometry. In combination with an appropriate
experimental setup, it is even possible to make the ultrasonic transmission through a wood …
