Paper Abstract

The model describes the reflection, refraction and absorption of light rays by a single cylindrical filament according to the classical laws of optics. The overall light transmittance and reflectance of a single filament are then assumed to apply to an entire layer of such filaments. The optical behavior of the entire filament assembly is derived by adding successive filament layers, with the same optical characteristics, to those already present. The model describes the effects of varying the relative refractive index of the filament material and the filament radius on the transmittance and reflectance of the filament matrix, and in individual filaments, influences the perceived color depth. The dye may be evenly distributed throughout each filament or located in a ring close to the filament periphery. The model also considers the case where filaments near the surface of the assembly are colored while those in the interior are not. The results are discussed in relation to practical coloration experience.
