X Ray Ptychography

X-ray ptychography is a computational imaging technique that reconstructs high-resolution images from multiple overlapping diffraction patterns, overcoming limitations of traditional lens-based microscopy. Current research emphasizes accelerating reconstruction speed and improving robustness to noise through the development of novel algorithms, including deep learning approaches like neural networks (e.g., vision transformers, unrolled iterative methods) and physics-informed models that leverage the underlying physics of the imaging process. These advancements are significantly impacting various fields by enabling faster, higher-resolution imaging in applications ranging from materials science and nanotechnology to biomedical imaging and non-destructive testing.
