Title: Multi-Modal Ptychography: Recent Developments and Applications

Abstract

Utilisation of partially coherent X-rays in Coherent X-ray Diffraction Imaging (CDI) and X-ray ptychography have brought intense research and developments for the past few years. Generally, data reconstructions convergence can be achieved by considering to incorporate partially coherent X-rays in ptychographic iterative reconstructions algorithms. Recently, exploration of both X-ray probe and sample modes have been studied and it was suggested that sufficient constraints are required to achieve accurate data reconstructions due to the mathematical inseparability of multiple sample modes that are superimposed into a single set of ptychographic intensity patterns. Here we review the multi-modal ptychography that can be used as a new emerging technique to investigate dynamical sample systems with partially coherent X-rays by recent experimental and simulated demonstrations.

Figure 1. Figure 1.: The first three (n = 1, 2, 3) recovered probe modes for the cases of (a) a static sample; (b) a square wave with amplitudes 1 µm and (c) 1.5 µm; and (d) a sine wave with amplitudes 1 µm and (e) 1.5 µm. The bottom line alsomore » shows the square root of the summed intensity (rms, right column, linear scale) from five probe modes for the cases listed previously. The rms shows clearly how the probe forms can be manipulated using a vibrating sample. The scale bar is 1 µm. The vibration frequency is selected to be 1 Hz with exposure of 6 seconds per position.« less
