Abstract

Ultrasonic techniques are applied to the measurement of wooden members to identify localized anomalies internal to the wooden members substantially smaller than the full width of the ultrasonic beam. Multiple spatially displaced measurements allow generation of comprehensive maps of the wooden members to aid in computer cutting and grading of the wooden members.
