Abstract
Ultralydteknikk anvendes på målingen av treelement (10) for å identifisere lokale uregelmessigheter i treelementets (10) indre, som hovedsakelig er mindre enn den fulle bredden til ultralydstrålen (48).Ultrasound technique is applied to the measurement of wood element (10) to identify local irregularities in the interior of the wood element (10), which are substantially smaller than the full width of the ultrasonic beam (48).
