Light Scattering Intensity Fluctuations in Microdroplets Containing Inclusions.
Abstract
A prominent characteristic of light scattered from a microparticle containing inclusions is fluctuating intensity due to changing positions of the inclusions with respect to each other and the host droplet. We calculate the magnitude of these fluctuations for a host sphere containing a single nonconcentric spherical inclusion and experimentally measure the fluctuation amplitudes for host spheres containing multiple inclusions. We find that for relatively small single inclusions, the amplitude of the scattering fluctuations increases approximately linearly with the area of the inclusion. For multiple inclusions, the fluctuation amplitude increases with concentration, with an approximate power-law dependence.
