Abstract
We consider optical systems composed of an arbitrary number of lenses and filters, separated by arbitrary distances, under the standard appr oximations of Fourier optics. We show that every such system is equiva lent to (i) consecutive filtering operations in several fractional Fou rier domains and (ii) consecutive filtering operations alternately in the space and the frequency domains.
