Parametric Modeling of Surface-Distributed-Scatterer Ensembles For Inverse Analysis of Diffuse-Reflectance Spectra

摘要

This study examines using parametric models for inverse analysis of diffuse IR reflectance from particulate materials thatare sparsely distributed upon a surface. Parametric models are applied for inverse analysis of simulated spectra, which arecalculated using ensembles of reflectance spectra for non-interacting material particles on surfaces, which have specifieddielectric response properties and particle-size distributions Simulated reflectance spectra for individual particles uponsurfaces, used for prototype inverse analysis, are calculated numerically using a model based on Mie scattering theory,which assumes spherical particles on surfaces. Parametric models of diffuse reflectance spectra provide encoding ofdielectric response features for physical interpretation and convenien representation.
