Abstract :
Ultrasonic inspection of solid wood and lumber has been investigated for over 20 years, with limited commercial impact. Potential applications run from logs to finished boards, with the goal of either characterizing internal defects (knots, splits, rot), or assessing overall strength. This paper reviews recent efforts to apply ultrasound technology to the Forest Products industry
