Parametric Reduced Absorption Spectra for NIR-SWIR Absorbing Dyes on Paper Substrate

Abstract

This study describes construction of reduced absorption spectra for NIR-SWIR absorbing dyes on paper, which is by critical feature isolation and projection. The critical features are identified through a structural analysis of the peaks, troughs, and points of inflection in the calculated Kubelka-Munk absorption spectra, from diffuse reflectance measurements. These features are then parameterized and projected into a reduced feature subspace to effectively capture the fundamental characteristics of the absorbing dyes. The critical feature parameterization and projection supports the construction of parametric models capable of estimating dielectric functions for various dyes, substrates, and mixtures.
