Abstract

We have investigated the effect of size distribution of aqueous solutions of monodisperse and a mixture of polydisperse scatterers of two different sizes on the image quality using linear and circularly polarized light. The contrast and resolution are affected by the size distribution present in the mixture of a polydisperse medium, while they are affected by the refractive index in a monodisperse medium. Circularly polarized light improves image quality of polydisperse scatterers. Images in the polydisperse medium are retrieved for values of optical thickness less than those of the large-sized monodisperse medium. We offer plausible explanations for all the experimental observations.
