Paper Abstract

We describe and analyze the experimental realization of the speckle interferometry scheme designed to measure deformation of an object surface. It can be shifted along the surface itself as well as turned or inclined. In contrast to the classical speckle interferometric schemes, we use a specially formed two-dimensional pattern of random binary structure as a speckle structure. The pattern being illuminated by the white light is photographed with the use of a digital camera. Further processing of the information related to the Fourier transformation of the pictures registered and determination of the obtained fringe structure period is carried out in PC.
