Lumber Defect Detection by Ultrasonics.

Abstract

Ultrasonics, the technology of high-frequency sound, has been developed as a viable means for locating most defects in lumber for use in digital form in decision-making computers. Ultrasonics has the potential for locating surface and internal defects in lumber of all species, green or dry, and rough sawn or surfaced. (Author)
