Abstract
An effect of rigid body rotation for the speckle image correction for electronic speckle pattern interferometry using DIC is investigated. The relationship between rigid body rotation and the change of static speckle pattern by single beam illumination is compared with the relation of rigid body translation and the change of static pattern. Additionally, the elimination of the interference fringe caused by rotation is examined by the position and the phase correction of the speckle image. Results show that the intensity error of the static speckle pattern by rotation is larger than the intensity error by translation, and the fringe pattern by rotation can be eliminated by the correction in the rotation range less than 10-3 rad.
