PtychoPINN framework enables single-shot imaging at light sources

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called PtychoPINN that enables single-shot, overlap-free ptychographic imaging, a significant advancement for coherent diffractive imaging. This technique couples a differentiable forward model of coherent scattering with a Poisson photon-counting likelihood, allowing for accurate reconstructions even with low photon counts. The new approach accelerates conventional multi-shot ptychography and has demonstrated superior performance compared to data-saturated supervised models, while also generalizing to unseen illumination profiles.

    Towards single-shot coherent imaging via overlap-free ptychography

    arXiv:2602.21361v3 Announce Type: replace-cross Abstract: Ptychographic imaging at synchrotron and XFEL sources requires dense overlapping scans, limiting throughput and increasing dose. Extending coherent diffractive imaging to overlap-free operation on extended samples remains …
