With the development of the technologies on modern photoelectron and computer technologies and the improvement on theory of digital image processing, Digital Speckle Correlation Method (DSCM) is rapidly emerging as a powerful research tool for experimental mechanics techniques. In this paper, the essential principle of DSCM is introduced and the applications of DSCM to wood science and technology, including the latest results of the test on general mechanical properties, fracture properties, micro-structural mechanical properties and the mechanical properties of wood and wood composite materials, are reviewed. Considering the characteristics of wood materials, some suggestions are proposed on the application of DSCM to wood science and technology.
