Abstract
One of the most important optical signal processing operations is the optical Fourier transform (OFT). Of the arrangements for
implementation of the OFT, perhaps the most flexible is that for the scaled optical Fourier transform (SOFT), as it allows control over
the scale of the output Fourier transform distribution. By means of an analysis in cylindrical coordinates, we examine some of the practical
limits introduced by the use of a thin lens of finite aperture in the implementation of the SOFT. Using simple rules of thumb that are
based on an examination of the phase and magnitude deviations from the ideal (infinite-lens) diameter case, we define a volume inside the
geometric shadow, which we refer to as a sub-geometric shadow. We then show that inside this sub-geometric shadow errors introduced
by diffraction can be quantified.
