abstract = "The purpose of the project described here is to
provide a graphic demonstration of the role of phases
and amplitudes in determining the appearance of printed
characters. The images of two printed characters are
Fourier analyzed and the amplitude spectrum of one is
combined with the phase spectrum of the other. In the
resulting hybrid image, one can clearly recognize the
letter whose phase spectrum is used, while no trace of
the other letter is evident. This procedure is also
carried out with letters of different fonts and sizes.
Again, the resulting images are mainly determined by
the phase spectra. However, with letters of different
sizes, the amplitude spectra, as one might expect,
influence the appearance.",
