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.
