Ptychography is a technique which is closely related to coherent diffraction imaging. Instead of recording just one coherent diffraction pattern, several - and sometimes hundreds or thousands - of diffraction patterns are recorded from the same object. Each pattern is recorded from a different area of the object, although the areas must overlap with one another. Ptychography is only applicable to specimens that can survive irradiation in the illuminating beam for these multiple exposures. However, it has the advantage that a large field of view can be imaged. The extra translational diversity in the data also means the reconstruction procedure can be faster. Ambiguities in the solution are also reduced.
