ABSTRACT:
A signal representative of the total incident flux on each area element of a target plane is generated. Each area element corresponds to a portion of the object from which the flux emanates. Each total incident flux signal is corrected to eliminate therefrom the effects of flux incident on the corresponding area element due to scattering, thereby to generate a signal representative of the flux incident on that area element emanating only from the portion of the object corresponding to that area element. The total incident flux signal is corrected by weighting each total incident flux signal in accordance with a predetermined weighting factor W(x,y), and summing the weighted signal representative of the total flux incident on an area element with a weighted total incident flux signal from each of the other area elements.
