description:
	measurement of coherent diffraction near a suitable Bragg peak of nanowire samples manifests a sensitivity to stacking faults within the lattice of the crystal.  This takes the form of a one dimensional speckle pattern formed by random distribution of faults along the length of the wire.  Traditionally speckle patterns are difficult to invert to images using the standard methods.  The new development in the field, known as Ptychographic Iterative Engine, takes advantage of speckle measured from overlapping regions of the sample to give the inversion rebust convergence.  Ptychographic data sets from such nanowire samples will be measured and inverted.
