Abstract
A description is given of an integrating-sphere-type instrument for measuring volume reflectance and volume transmittance of a thin plane-parallel slab of gelatin having scattering particles embedded within it when uniformly diffuse radiation is incident on the slab. Fresnel surface reflections are eliminated by immersing the slab of gelatin in a liquid matching the refractive index of gelatin. The liquid consists of a mixture of 73% bromobenzene and 27% Nujol Extra Heavy Mineral Oil. The theory of the instrument is outlined.Keywords
