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.
叠层成像术已成为一种无损工具，可在高空间分辨率下对扩展样本进行定量研究。在本论文中，我们报告了我们团队的最新进展。我们将低温叠层成像术与荧光显微镜相结合，以同时观察超微结构和元素组成；我们开发了多GPU并行计算以加速叠层成像重建；并且我们实现了飞扫叠层成像术以实现更快的数据采集。我们最后讨论了高分辨率三维叠层成像术未来面临的挑战。
