9.1 INTRODUCTION
An electromagnetic signal is described by its amplitude, state of phase,
and state of polarization. Such signals are found in very dierent branches
of science, such as electronics, telecommunication, interferometry, ultra-
sound, and phase-contrast x-ray tomography. Although the amplitude of
the signal is easily accessible through the measurement of the intensity with
a power detector or camera, retrieving the phase from intensity measure-
ments (images) is more involv ...
