This study deals with the measurement of the two-dimensional deformation of wood joints under compressive loads using an electronic speckle pattern interferometry (ESPI) technique. A mortise and tenon joint and a dovetail joint of western hemlock are used as specimens. Results reveal that a large two-dimensional deformation of the wood joints can be measured using the ESPI technique, the deformation values significantly vary with parts, and the accuracy of the fabricated wood joints has a significant effect on the two-dimensional deformation of the wood joints.
