Optical correlation measurements of the structure parameters of random and fractal objects

The state-of-the-art of optical correlation diagnostics of random phase objects is considered both in the framework of conventional notions of the theory of probability and using the concepts of chaotic oscillations theory. A promising fractal approach for the object structure diagnostics is discussed. In particular, the possibility of estimation of the Cantor fractal's dimensions through measurement of a correlation dimension of complexity at the diffracted optical field is shown. This possibility is realized using an original technique for the measurement of a complexity at optical fields.
