On the inverse problem in radiative transfer

Abstract
The inverse problem in monochromatic radiative transfer is considered for an infinite medium with anisotropic scattering. It is shown that each Legendre coefficient of the scattering function can be related independently of the others to an appropriate integral over space and angles of the intensity due to a monodirectional plane source. This result offers some advantage over the analogous one for an isotropic plane source if the medium is weakly absorbing.
