Method for inhomogeneous media probing ny means of the contrast measurements for multiply scattered speckles is considered. Value of the speckle contrast is obtained on the basis of the discrete scatter model as the integral transform of probability density function of differences of effective optical paths characterizing the scattering system. Pathlength distributions were simulated for different detection conditions and optical properties of scattering medium by using Monte-Carlo technique. Comparison of the discussed approach with traditional method of diagnostics and visualization of turbid media such as direct measurements of the scattered light intensity is made.
