| Abstract: | Radiation intensities in an isotropically scattering slab irradiated by a cylindrical beam have been obtained by numerical solution of the radiative transport equation in two dimensions. In contrast to the usual one-dimensional solutions, solutions to the two-dimensional case provide a basis for the use of a narrow diagnostic beam to examine optically-thick media. It is shown that measurements of the intensity of radiation scattered from a narrow beam in an optically-thick slab, as well as of the transmitted beam, can be used to deduce the albedo and the optical thickness. |
