Abstract

Effect of objects buried in highly dense media on the properties of angular intensity correlation of the scattered light is investigated by means of a theoretical approach and numerical simulations. In the case of an object located just behind the scattering medium, a Fourier transform relation between the angular correlation function and the intensity distribution in the illumination plane where the object exists is derived theoretically for transmitted light. When the object is buried in the medium, such a boundary condition is not satisfied, and it was found from the simulation results that the effect of the object on the angular correlations can be observed more strongly for the object being somewhat deep rather than near the output surface. For reflected light, on the other hand, the influence of the object on the angular correlation function becomes small because of a scattering component not reaching the object.
