Abstract
It is shown that it is possible, in principle, to recover the strip distribution of brightness aeross a radio source from the Fresnel diffraction pattern which is observed. as a. source is occulted. Practically useful methods of approximating to this ideal 8.1'&. indicated. Rather surprisingly, the resolution attainable in the presence of a given noise level is not related to the angular width of the first Fresnel zone, but is just the same, as it would be if geometrical optics were valid.https://doi.org/10.1071/PH620333
