The workshop focuses on modern challenges in inverse problems involving coherent X-ray light, typically from synchrotron source but not exclusively; near and far field ptychography, phase contrast imaging, holography and their extension to three dimensions through tomography. We will focus on bridging the algorithmic design and challenges unique to practical applications arising in high resolution imaging, such as phase retrieval, large data, partially coherent illumination, structured illumination, geometrical errors and other stability issues. The workshop focuses on scalable mathematical approaches to deal with such issues; the optimization framework and computational constraints stemming from large amounts of data and hardware limitations.

Topics:

• • Inverse problems in coherent X-ray imaging

  • Phase retrieval and tomography

  • Large-scale and distributed optimization

  • Algorithms for coherent and structured illumination

  • Computational scalability and real-time reconstruction

  • Robustness to noise, geometry, and hardware imperfections

  • Applications to tomography and 3D imaging
