摘要：

We emphasize the diffraction properties of cylindrically symmetrical first order systems. Based on matrix optics, our investigations lead to two conclusions. One is that diffraction of such a lossless system consists of a fractional Fourier transform. The other is that the fractional order of the system is not unique. It depends on the concrete implementation of a diffraction system.
