This paper takes the theoretical results of the first paper [ Appl. Opt.29, 4646 ( 1990)] and develops the idea of image formation using the diffractive process from Ref. 1 in terms of the point-spread function and the transfer function for both coherent and incoherent light. Theoretical and experimental comparisons are made for two-point resolution and imaging of extended objects. In addition, image formation with a sphere is compared with conventional image formation with a lens.
