Diagnosis of Internal Defects of Wood With Stress Wave Tomography
Internal defects of Chinese Fir and Euphrates Poplar were evaluated through imaging recognition by stress wave tomography.Results showed stress wave tomography was an effective method in diagnosing internal defects in wood.Defect information,such as dimension,location and shape,could be reconstructed through 2D image velocity matrix.The stress wave tomography provided a useful reference for assessing the stability of tree trunks,but it did not accurately distinguish between decay and hollow areas in the wood.
