Light scattering by a sample with polished surface

Abstract

The use of spectrophotometric references under conditions that differ from CIE recommended illumination and viewing geometries is possible only if the bidirectional reflectance function is known. One of the materials used for realization spectrophotometric primary transfer standard is milky glass with polished surfaces. A model that describes scattering of light by a similar object is proposed in this study. The comparison between theoretical results and experimental data is carried out. In view of the results of modeling, a perspective of creating a method of goniophotometric calibration of Russian opal glass for any illumination and viewing condition is discussed.
