Image formation of a self-Fourier object.
A function that is its own Fourier transform is coined a self-Fourier function. The complete set of self-Fourier functions has been recently defined by Caola [J. Phys. A: Math. Nucl. Gen. 24, L1143-L1144 (1991)]. We study the behavior of a self-Fourier function as a self-imaging function. The space-bandwidth product of these functions is studied. An illustration of a self-Fourier function that was a Wigner distribution function is given. Some experimental results are also presented.
