Light Scattering From A Drop With An Embedded Flake: Application To The Time-Shift Technique

 

Abstract:

This study is devoted to computing the light scattering from drops with an embedded, reflecting flake, as encountered with metallic paints. Such drops are typical in the automotive industry and a complete knowledge of scattering characteristics is a prerequisite to optically measuring the drop size and velocity and to determine whether the drop contains a flake or not. The light scattering is computed using a ray tracing method. Once the light scattering has been computed, this information can be used to simulate the response of specific instru-ments. In the present case the signal generation of a time-shift instrument has been exemplary studied.
