| Abstract: | A metrical method for object displacement was introduced, which was based on digital image processing in the paper. Speckle images with white light diffraction of any time or state recorded were by CCD during the movement of loaded element, then the results of displacements were measured in virtue of current techniques of image processing and retrieval. |
