| Abstract: | Non-destructive testing for defects is an important technology for utilizing of wooden material effectively and reasonably. Facing the shortage of wooden material in the world nowadays, the effective non-destructive testing for wooden material's defects appears importance. The main course of researches on non-destructive testing for wooden material's defects is reviewed, including the imaging technique, the changing of signal propagation velocity, defects of manual simulation, signal processing of non-destructive testing for wooden material's defects and influence of wooden material's defects upon mechanical property. Then the existing problems of non-destructive testing for wooden material's defects are analyzed in brief,and development tendency is forecasted. |
