Paper Abstract

In this paper we present a scheme for ghost imaging based on partially coherent light produced when coherent light passes through a turbid medium. The light is described by a transport model incorporating Mie scattering theory. Using this model it is possible to predict the second order correlation function of the pseudo thermal source and to estimate key parameters for its application in ghost imaging experiments. Analytical and numerical simulations of the second order coherence function are performed in terms of scattered and un-scattered components of the light. The coherence length of the scattered component, responsible for ghost images formation, is determined in terms of concentration and diameters of the scattering elements. The advantage of using this type of source with respect to previous experiments is a better understanding of its coherence properties responsible for resolution and visibility of ghost imaging with thermal light.
