Abstract

Double passage imaging through discrete random medium with large particles is under study in this paper. The effect of correlation of the illuminating and return waves, which occurs due to passage of the waves through the same randomly distributed scatterers, on the object image is analyzed. It is shown that correlation of the opposing waves can lead to significant 'enhancement' of the coherent component of the optical image and can enable us to observe the distant objects in turbid media which are indistinguishable in discrete medium under side illumination when such correlation is absent.
