| Abstract: | Digital image correlation (DIC) is considered as an advanced optical and deformed measured method to be an important tool in the field of wood science. This paper summarized the characteristics and principles of DIC, and expounded its application to the field of wood science, mainly including the determination of wood mechanical property, the measurement of deformation after wood drying and the studies on related property of other wood-based materials. Finally, the opportunities and challenges that could be met in wood science study were prospected. |
