Position-Blind Ptychography: Viability of image reconstruction via data-driven variational inference

arXiv:2509.25269v3 Announce Type: replace-cross Abstract: In this work, we present and investigate the novel blind inverse problem of position-blind ptychography, i.e., ptychographic phase retrieval without any knowledge of scan positions, which then must be recovered jointly with the image. The motivation for this problem comes from single-particle diffractive X-ray imaging, where particles in random orientations are illuminated and a set of diffraction patterns is collected. If one uses a highly focused X-ray beam, the measurements would also become sensitive to the beam positions relative t
This publication represents a incremental technical advancement in the field of computational imaging, a routine academic output from research labs.
For a strategic reader, this specific technical paper holds little direct importance as it addresses a niche problem in scientific imaging, far removed from immediate geopolitical or economic relevance.
This research potentially refines the methodology for specific scientific imaging techniques like single-particle diffractive X-ray imaging, but it does not fundamentally alter broader scientific or technological landscapes.
Improved accuracy in certain scientific imaging applications could result from wider adoption of such techniques.
Better imaging might aid in materials science or biological research, indirectly supporting broader scientific discovery.
These detailed imaging capabilities could eventually contribute to the development of new materials or medical diagnostics, but this is highly speculative and long-term.
