Abstract
In this work we present a solution for the boundary problem for phase retrieval techniques based on the Transport of intensity Equation (TIE). The solution presented here is based on the Neumann Boundary condition and the mirror padding scheme of the captured intensities. The obtained results are derived for the widely used Fourier Transform based TIE solver, but it is shown that they can also be applied to Multigrid based techniques. Full Text: PDF References K. A.
