Modeling images of phase information for three-dimensional objects

In this work we present a model that describes the electric field in the image plane of a transparent 3D object. The imaged object is modeled as a stack of independent planes along the optical axis and the phase from all the object planes at the image plane is considered as a superposition of the 2D phase contributions from all slices. The object is defined as a phase transmission function and the backscattered field is neglected. We present and discuss examples of simulated data for 3D objects with phase variations along the optical axis.
