Masking of Light Scattering Information on Matrix Elements from Complex Scattering.

Abstract

Changes in light scattering curves due to perturbation on scattering systems are considered, using both measured data and, where possible, computer generated data. It is demonstrated that polydispersivity in size or real refractive index quickly destroys phase information from systems of perfect spheres, while absorption destroys phase information mainly in the backscatter directions and decreases the ratio of backscatter to forward scatter intensity. Several measured Mueller matrices are presented for perfect, bent, rotated, tilted, and surface roughened fibers, and for a highly irregular scatter, road dust. An introductory tutorial on the Mueller matrix description of light scatterings is included. Keywords include: Light scattering; Mueller matrix; and Masking.
