Paper Abstract

In the present paper physical bases of a new direction in interferometry - laser interferometry of random inhomogeneous objects, within the framework of which in difference from classical interference methods as a measuring signal not the form of interference fringes or dynamics of their change, and contrast of fringes carrying the information o statistical parameters of object are considered. The interference of identical and non-identical partially developed speckle-fields is studied. The dependencies of contrast of mean-intensity holographic interferometers. The possibility of using spatially modulated laser beam to determine statistical parameters of scattering objects, namely, the phase variance, the correlation length, and the form of the coefficient of correlation of optical inhomogeneities, is considered.
