Application of the Allen–Oxley iterative method of phase retrieval to series of images obtained by focus variation

Descripción del Articulo

The application of the iterative method of phase retrieval to series of images obtained at different defocus values is described and discussed. It is shown that the iterative scheme is robust in the presence of discontinuities in the phase. The application of these methods to a set of experimental i...

Se muestra que el esquema iterativo es robusto en presencia de discontinuidades en la fase. La aplicación de este método a un conjunto de imágenes experimentales tomadas usando rayos-X es investigada.
