In the previous paper, we proposed full field motion compensation techniques based on the digital image correlation method. One of these techniques used only sequential infrared images, and motion compensation was conducted based on the movement of artificially introduced speckle pattern on the sample surface. The motion compensation requires infrared data acquisition twice in the same loading condition, one for the motion analysis and the other for thermoelastic stress analysis. Therefore, this technique had a limitation for random loading or impact loading application. To eliminate the limitation a new motion analysis method is proposed based on the movement of natural speckle emmisivity pattern generated due to the nonuniformity of the thickness of flat black paint. The usefulness of the proposed method is demonstrated.
