Light scattering by arbitrarily oriented optically soft spheroidal particles: Calculation in geometric optics approximation

Methodology of calculation of coherent and non-coherent light scattering by arbitrarily oriented optically soft spheroidal particles in geometric optics approximation is presented. The aim of this work is to develop an instrument for quick calculation of scattering patterns from particles modeling red blood cells and their aggregates. Results of calculation describing the dependences of scattering patterns on refractive index, eccentricity and orientation of an ellipsoidal particle with size parameter about 40 are presented.
