Abstract

An iterative Fourier-transform algorithm was implemented to reconstruct the phase function of an imaging system using a point source (a single mode ber) and extended sources (pinholes) as the object. The results indicate that as the objects size is increased the phase retrieval is largely unaected until it grows to a critical diameter. At this point the phase retrieval results become highly unstable. The critical diameter at which this transition occurs is considerably smaller than predicted by the Rayleigh criterion. In this paper, we will present a detailed description of the imaging system, the source objects and the experimental results.
