We first discuss the discrete Fresnel transform and present some essential properties. We then propose a recursive algorithm to implement phase retrieval from two intensities in the Fresnel transform domain. This approach can significantly simplify computational manipulations and does not need an initial phase value compared with conventional iterative algorithms. Simulation results show that this approach can successfully recover the phase from two intensities.
