| Abstract: | There exist in the literature a number of theories to estimate the diffuse reflectance values of materials varying in their optical properties. In this article, an analysis of some of the theories has been made with a view to assess the dependence of diffuse reflectance of materials on their optical constants and their grain size (d). |
| Keywords: | Diffuse reflectance Integrating sphere Internal and external reflection coefficients Optical properties Grain size |
