Paper Abstract

In this paper, three different surface theories are discussed that give the engineer wide flexibility in the types of surface reflection problems that can be analyzed. The first is a rigorous theory of surface reflection (based upon Maxwell's boundary conditions) that accurately treats reflection from flat surfaces with roughness that is small compared to wavelength. The second is a model similar to the Hopkins-Marechal approach to optical tolerancing that can be used to treat small angle scatter from various optical forms. The third model is one that correctly accounts for off-specular reflection peaks that sometimes occur on baffle type surfaces. The utility of these three models as well as their limitations to stray-light calculations will be discussed.
