OPTICAL CORRELATION-MEASUREMENTS OF THE STRUCTURE PARAMETERS OF RANDOM AND FRACTAL OBJECTS

The state-of-the-art of optical correlation diagnostics of random phas e objects is considered both in the framework of conventional notions of the theory of probability and using the concepts of chaotic oscilla tions theory. A promising fractal approach for the object structure di agnostics is discussed. In particular, the possibility of estimation o f the Canter fractal's dimensions through measurement of a correlation dimension of complexity at the diffracted optical field is shown. Thi s possibility is realized using an original technique for the measurem ent of a complexity at optical fields.
