| Abstract: | As a newly current advanced analysis technology,the near-infrared(NIR)spectroscopy possesses advantages of easy operation,fast and accurate detection,low cost and non-destructive test, has been widely used in the fields including pulp manufacturing and paper-making,wood properties estimation,wood progressing,wood composites producing and wood protection.In present work, based on introduction of the basic principles of NIR and its main characteristics,an overview was conducted focusing on the research status of wood anatomical characteristics(including cellulose crystallinity,microfibril angle and fiber morphology) estimation by using NIR spectroscopy.Moreover, the application trends were prospected. |
