Abstract:

We discuss here imaging of an object illuminated through a discrete large-scale random medium. The effect of correlation between the illuminating and return waves passed through the same randomly distributed scatterers on the object image is analyzed. It is shown that correlation of the counter waves can lead to a significant enhancement of the coherent component of an optical image and can enable us to observe distant objects in turbid media which are indistinguishable in a discrete medium under lateral illumination when no such correlation occurs.
