A method for comparing and reconstructing two nearly identical
planar objects that are composed of the same number of identical
apertures is presented. These structures differ only in the
location of one of the apertures. The method is based on a
subtraction algorithm, which involves the cross-correlation and
autocorrelation functions of the compared structures. Simulated
results illustrate the feasibility of the method.
