The correlation of intensity fluctuation of light waves on scattering from a particulate medium

The higher-order coherent effect of light waves on scattering from a collection of particles has been discussed within the accuracy of the first-order Born approximation. It is shown that the correlation of intensity fluctuation (CIF) of the scattered field is closely related to the characteristic of the collection of particles. An example of light waves on scattering from a collection of particles with Gaussian-centered distribution has been discussed, and the influence of the distribution characteristic on the normalized correlation coefficient of CIF of the scattered field has been studied. This result may provide a potential way to determine the distribution information of a collection of particles by measuring the intensity data of the scattered field.
