Abstract

A transmission type of experiment was set-up to investigate coherent light scattering on suspensions with scattering centers having a wider size distribution. For each sample the contrast, the average intensity and the average speckle size of the far interference field were calculated using an alternative simple algorithm that is presented in detail. The variation of the far field parameters with the scattering centers concentration is presented. A possible application in measuring the scattering centers concentration in the very small values range is suggested and the range is indicated.
