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.
