Advances and challenges in cryo ptychography at the Advanced Photon Source
Ptychography has emerged as a nondestructive tool to quantitatively study extended samples at a high spatial resolution.In this manuscript, we report on recent developments from our team. We have combined cryo ptychography and fluorescence microscopy to provide simultaneous views of ultrastructure and elemental composition, we have developed multi-GPU parallel computation to speed up ptychographic reconstructions, and we have implemented fly-scan ptychography to allow for faster data acquisition. We conclude with a discussion of future challenges in high-resolution 3D ptychography.
