Abstract

Phase retrieval techniques have been used for the measurement of 3-D objects. The phase of the transmitted or reflected light beam is modulated by different characteristics of the object and reveals valuable information. The multi-plane diffraction iterative algorithm is a method of phase retrieval with a single beam. Based on numerical phase-error correction system, the method obtains the phase and amplitude of a wavefront with a sequence of intensity patterns recorded at different planes. There are various parameters involved in this method. The parameters impact the retrieval in common. For the optimization in implementation and guidance to experiments, we study six parameters of this method by a series of simulations. The six parameters are the number of sampling planes, the round trip number of iterative, the initial phase, the distance between the object and the first sampling plane, the distance between sampling planes and the wavelength. A discussion on the result of the simulations is also presented.
