| Abstract: | Calculations are presented for second-order fluctuations of Stokes parameters that result from singly scattered, coherent, polarized radiation by an ensemble of small spheroidal particles which are randomly oriented in space. The form of the second-order non-Gaussian enhancements are obtained and discussed, but attention is also given to terms describing amplitude fluctuations that are present in the Gaussian scattering regime. These terms provide a generalized Siegert relationship for polarized radiation. The possibility of using measurements of fluctuations to characterize the particle shape is considered. |
