Abstract : A model of the imaging process in neutron radiography has been employed to determine the edge-spread function for a given radiographic system. As an aid to the numerical evaluation of this function, approximate analytical representations of the resolution function have been examined. This has facilitated the formulation of an analytical technique for determining the effects of neutron beam divergence. Comparisons are presented between computational results and a series of experiments designed to test the validity of the theoretical model. The agreement obtained is very satisfactory. (Author)
