Phase imaging with a half-plane aperture.
A method that effects phase reconstruction from a single image of a phase object is presented. The method, which is founded on the iterative transform algorithm, more specifically the error reduction version of this algorithm, applies this algorithm in an unusual way, in that it attempts to solve the phase problem from the measurement of a single image of the object taken by using a half-plane aperture rather than its diffraction pattern. A description of the method, an analysis of its performance, and suggestions as to its potential application are given.
