Abstract = {{In this paper, the state of polarization of a quasi-monochromatic beam
   diffracted by a perfect crystal in the Bragg geometry is described in
   the framework of standard concepts of optics:  the polarization transfer
   function (PTF), the coherence matrix, the Stokes decomposition, and the
   Mueller matrix.  From simulations based on the dynamical theory of X-ray
   diffraction, we analyze how the phase and amplitude of the sigma and
   pi-polarization components vary during several successive reflections on
   perfect single crystals.  Different crystal arrangements are then
   compared from the point of view of their polarization transfer
   properties, i.e. the conventional double crystal (+, -) monochromator,
   the antiparallel (dispersive) four-crystal setting and another
   four-crystal configuration with two `'twisted'' two-crystal modules. 
   The latter is discussed carefully as it makes it possible, in principle,
   to recover high circular polarization rates (even at Bragg angles
   approaching 45-degrees) but at the expense of increasing losses in the
   transmitted intensity.  Of particular interest is the comparison of the
   polarization transfer properties of different crystal pairs, e.g.
   Si(111) or Ge(111) single crystals.  Finally, we call attention to the
   potential advantages of using asymmetric reflections.}},
