X-ray holography

A review of holographic methods using hard x-rays is presented. The main emphasis is put on those techniques which aim to produce atomic resolution. For this reason ʹthe inside source conceptʹ and its experimental realizations are discussed in detail. Apart from the general description of holographic imaging with atomic resolution, specific features such as the effect of multiple scattering, translation periodicity and angular dependence of the atomic scattering factor are also given.
