Measurement Science for Optical Reflectance and Scattering
Goals and Tasks
- Advance the science of appearance measurements by developing and integrating advances in
microstructure and reflectance measurements
microstructure and reflectance modeling
computer rendering
- Develop appearance-prediction models by integrating measurements and models in a computer rendering system to create a virtual accurate representation
The approach being used to meet the goals is shown in the figure. Corresponding measurements and modeling are being carried out in three major areas: Materials (properties of raw material components, microstructure and surface structure of coating films), scattering, and appearance. Two model systems are being used to demonstrate the approach. The first is a clear coating on a black substrate in which surface scattering is dominate. The second is a coating containing platelet pigments in which the optical scattering is strongly dependent on angle of illumination and viewing. Different colors represent efforts led by different laboratories, with the final steps in red to be taken through colaborations between NIST and industry.
