WebSep 7, 2024 · Scattering from particulate contaminants. All surfaces have some amount of particulate contamination (i.e., dust) that increases their BSDF above the level predicted by their surface roughness. It happened in a clean room when we are aligning a optical system. I would like to simulate this scattering using a MIE model, for that I need to give ... WebSep 1, 2024 · The software is intended to simulate light scattering by large aggregates of spheres, where the ensemble of scattering targets is larger than the width of the incoming light ray. The appropriate initial excitation for the simulations is thus that of a Gaussian beam (although plane waves are implemented, too).
WebOct 21, 2024 · Spatial frequency domain imaging (SFDI) is a wide-field, noncontact technique that quantitatively separates light absorption and scattering properties by photographing the diffuse reflectance of structured light projected onto the tissue [].The optical properties parameters can be used to characterize the transmission and … WebPhysics, Mathematics. A set of Mie functions has been developed in MATLAB to compute the four Mie coefficients an, bn, cn and dn, efficiencies of extinction, scattering, backscattering and absorption, the asymmetry parameter, and the two angular scattering functions S1 and S2. In addition to the scattered field, also the absolute-square of the ...
