Abstract
Abstract. The general effects of imperfections in measured data on image reconstruction are considered. The particular problem of phase recovery is discussed in some detail, both direct and iterative restoration procedures being examined. In several important applications of image reconstruction, measured data is sampled at a grid of points distinct from the grid most convenient for the reconstruction procedure. The difficulties likely to be encountered when carrying out the necessary interpolations are itemized and ways of ameliorating them are outlined. It is shown that the phenomenon of speckle has a bearing on both the phase problem and the interpolation difficulty, thereby forming a conceptual bridge between various computational niceties of phase recovery and image reconstruction.
