Hybrid inelastic-scattering models for particle thermometry: polarized emissions.

The work of a previous paper [Appl. Opt. 31, 7132 (1992)] is extended to the case of polarized inelastic (Raman and fluorescent) scattering from molecules embedded in spherical particles of large optical size parameters. The hybrid modeling technique, which combines the Lorenz-Mie theory with a geometric optics method, accounts for the contributions of directly transmitted rays as well as reflected-transmitted rays of secondary emissions. Coherent effects of light rays emitted from a single point source are considered in the model. The angular scattering patterns predicted with the modeling technique are consistent with expected physical behavior and results from classical solutions. This work has a direct impact on studies of particle thermometry and particle diagnostics in which inelastic-scattering techniques are beginning to be applied.
