Abstract
The possibilities of optical diagnostics of random phase objects are studied, based on measurements of transverse coherence function, scintillation index, and amplitude and phase dispersion of the field resulting from interaction with the object. The advantages of these methods over commonly used methods are increased speed and accuracy. Interference measurements of second- and higher-order correlation parameters of the field phase are demonstrated, which can be used to find the corresponding probability density distribution function for objects with phase statistics differing from Gaussian statistics. Also reported are results on the structure of phase-inhomogeneous crystals, rough surfaces, and plane-parallel plates.
