A novel technique of speckle photography has been applied to measure small deformation of a surface. A low-cost, commercial charge coupled device photo camera provides the images of speckle pattern through the beam splitter. Initially, a speckle pattern has been taken with the system at rest, and then second image captured after the deformation was made in the surface. By simple subtraction of the digital pictures, we obtain a fringe pattern that gives us information about the deformation.
