Multiple energy x-ray holography: the polarization effect
  We present the theory for Multiple Energy X-ray Holography (MEXH), using a multipole expansion for the scattered field. We find that light polarization plays a crucial role in the reconstruction of the image, and we suggest how to use it in order to eliminate aberration effects. The method we propose is alternative to the SWIFT method (scattered-wave--included Fourier transform), but has the advantage that no theoretical calculations are required to redefine the hologram.
