In order to reconstruct object-functions (material-density, spatial variation of a dielectric constant e.t.c.) from scattering data taken for different viewangles and wavelengths various mapping-configurations are in use. Proceeding from a model where coupling between the different infinitesimal parts of the scattering structure is neglected, the unknown object-function can be shown to be related to the scattering data via Fourier transform. Utilization of algorithms based on this assumption leads to distorted image functions caused by coupling effects ever present in reality. After discussing the influence of the imaging configuration on these distortions a method for reducing faults stemming from coupling-effects between spatially seperated parts is proposed.
