Abstract
The inverse Fourier transform is performed on the focused aerial image to find the time-domain representation from the frequency domain. In this paper we proposed a modified hybrid input-output algorithm for phase retrieval to generate the computed image satisfies the object-domain constraints. Generally the iterations continue until the computed Fourier transform satisfies the object-domain constraints in case of hybrid input-output algorithm. The proposed algorithm was effective in the early iterations for stripe pattern or line and space pattern images. In our experiment we obtained the fast convergence for the images by introducing the proposed algorithm to the typical hybrid input-out algorithm.
