To precisely measure the heating metallic deformation, an experimental platform based on the principle of laser electronic speckle pattern interferometry(LESPI)was proposed. After image processing, the three-dimensional displacement of deformation was obtained. To optimization the results, the laser was disposed and the effects of measurement with different roughness objects were contrasted. The results showed that better specklegram will be obtained with laser after pinhole filter and objects with higher roughness. The research provides experiment method for the metallic deformation measurement and reference to improve measure accuracy.
