The Earth’s atmosphere is an environment replete with particles of differ-ent sizes with various refractive indices which affect the light radiation traveling through it. The Mie scattering theory is one of the well-known light scattering techniques ap-plicable to modeling of electromagnetic scattering from tiny atmospheric particles or aerosols floating in the air or within the clouds. In this...

Background Light sheet microscopy became a popular tool allowing fast imaging with reduced out of focus light. However, when light penetrates turbid media such as biological tissues, multiple scattering scrambles the illumination into a speckle pattern and severely challenges conventional fluorescence imaging with focused light or with a light sheet. In this article, we present generation of li...

The applications of elastic and quasi elastic light scattering techniques to polymers in dilute solution, thermotropic liquid crystals and biological membrane vesicles are presented. It is focused on how we extract specific structural features or dynamic processes of these condensed medium samples through the light scattering methods. The paper reviews the light scattering studies that were car...

We present a new approach to probing single-particle dynamics that uses dynamic light scattering from a localized region. By scattering a focused laser beam from a micron-size particle, we measure its spatial fluctuations via the temporal autocorrelation of the scattered intensity. We demonstrate the applicability of this approach by measuring the three-dimensional force constants of a single b...

By studying cross correlations in the intensity of light scattered by a fluid sample in different directions at different times, it is possible to measure the dynamic scattering function S(k,t) for the fluid. The multiple scattering contribution to the time-dependent cross correlations is very substantially less than the multiple scattering contribution to S(k,t) as obtained by a conventional s...

Dynamic light scattering is a well established technique currently used to determine the average hydrodynamic diameter of nanometer to micrometer particles in suspension. A simple, modified experimental setup and the software to process experimental data are presented in this paper. Results on monitoring the time variation of the average diameter of the particles in suspension are presented and...
