Abstract:

The National Institute of Standards and Technology (NIST) is conducting a study to advance the science of measuring and modeling the optical scattering properties of materials. Results of measurements and mathematical models for quantifying light scattering from a material are being used as input for computer rendering models and procedures for determining appearance characteristics. The study will advance the characterization of spectral, goniophotometric and textural properties and improve the understanding of the interactions between light and the microstructural properties of materials. The measurement techniques and the models will be generally applicable in ecommerce and in the design, manufacture and sale of materials. This paper will briefly discuss preliminary results of a systematic study on metallic pigmented coating materials using laser scanning confocal microscopy and optical scattering.
