摘要：

The characteristics and properties of fractional Fourier transforms of an arbitrary degree, as implemented by a lens system, are presented. We describe the perfect imaging process and implement it by cascading a set of appropriate fractional-Fourier-transform elementary units of integer and/or fractional degree, forming generalized afocal systems.
