Abstract: The speckle correlation method is an optical method measuring the displacement. The initial and the deformed speckles of the model surface are taken，and the displacement can be obtained by the digital image process technology. The software is designed for the ease of operation throughout the visualization. The user can easily choose the target areas and different searching windows. The intervals of the output points can be easily adjusted. The graphical pixels can be converted into the actual length and the Y axis can be changed to opposite direction. Displacement results are preserved in text format, and documents can be easily opened.

Key words: Speckle Correlation Method, Software Design, Displacement Measurement, Image Proces
