TLDR
In this article, a general treatment of the scattering of radiation by an inhomogeneous material is developed, where scattering measurements can be used to obtain the average square of the fluctuations in refractive index or electron density and a correlation function which measures the degree of correlation between two fluctuations as a function of their distance of separation.Abstract:
A general treatment of the scattering of radiation by an inhomogeneous material is developed. It is shown how scattering measurements can be used to obtain the average square of the fluctuations in refractive index or electron density and a correlation function which measures the degree of correlation between two fluctuations as a function of their distance of separation.The scattering of visible light by Lucite and two glass samples has been investigated. The data are analyzed in terms of the quantities mentioned above. It is found that the extensions in space of the inhomogeneities in the Lucite sample are much greater than those in the optical glass samples investigated. The magnitudes of the fluctuations in refractive index are found to be dependent on the composition of the sample.read more

Scattering by an Inhomogeneous Solid. II. The Correlation Function and Its Application
TL;DR: In this paper, the angular intensity distribution of x-rays scattered by porous materials (hole structures) in the range of small angles is characterized by an exponential correlation function in the case of a distribution of holes of random shape and size in solid; a theoretical derivation of the exponential function is given for this case.

Characterization and Analysis of Porosity and Pore Structures
TL;DR: There are a large number of methods for quantifying porosity, and an increasingly complex idea of what it means to do so as discussed by the authors, which is why it is important to quantify the relationships between porosity and storage, transport and rock properties, however, the pore structure must be measured and quantitatively described.

TL;DR: In this article, the static scattering intensity distribution I(q) of microemulsions is obtained from a Landau theory, which includes a negative gradient term in the free energy expression.

A Photoelectric Instrument for Light Scattering Measurements and a Differential Refractometer
TL;DR: In this paper, an instrument for light scattering measurements on polystyrene solvents is described, which measures transmission and scattering of light at 90°; two different schemes can be employed to obtain the angular intensity distribution of the scattered light, and a compensating refractometer which is used to determine the difference in refractive index of solvent and solution.
