First-Order Parametric Model of Reflectance Spectra for Dyed Fabrics
Abstract
This report describes a first-order parametric model of diffuse reflectance for the purpose of simulating the spectral response of military textiles containing different types and concentrations of near-infrared (NIR) absorbing dyes. This model should contribute to the development of prediction tools, which when given the constituent materials available, will provide for the design of optimal composite systems, i.e. military combat uniforms allowing individuals to match the environmental spectral response in the visual, near-infrared, and shortwave-infrared spectral bands. The dyes considered for prototype analysis using this model are triarylamine, tetraaryldiamine, transition metal dithiolene, and indolium iodide. The fabrics considered are camouflage textiles characterized by color variations. The results of this study provide validation of the constructed parametric model, within reasonable error tolerances for practical applications, including NIR spectral characteristics in camouflage textiles, for purposes of simulating NIR spectra corresponding to various dye concentrations in host fabrics, as well as potentially to mixtures of dyes.
