A method of determining interior three-dimensional movement, deformation and strain in an object is provided. The method includes constructing a reference volume image, constructing a deformed volume image, wherein the deformed volume image represents the object after an applied stress and strain. The method further includes comparing the reference volume image and the deformed volume image to determine at least one displacement vector at least one of the x, y, and z directions. In addition it includes making a comparison for size of speckle features measured within the object. Based upon the at least one displacement vector, interior three-dimensional movement, deformation and strain can be measured for the object resulting from the applied stress and strain. |
