    • Ptychographic X-ray speckle tracking 

      Morgan, Andrew J.; Quiney, Harry M.; Bajt, Saša; Chapman, Henry N. (Journal of Applied Crystallography, 2020)
      A method is presented for the measurement of the phase gradient of a wavefront by tracking the relative motion of speckles in projection holograms as a sample is scanned across the wavefront. By removing the need to obtain ...

    • speckle-tracking: a software suite for ptychographic X-ray speckle tracking 

      Morgan, Andrew J.; Murray, Kevin T.; Quiney, Harry M.; Bajt, Saša; Chapman, Henry N. (Journal of Applied Crystallography, 2020)
      In recent years, X-ray speckle-tracking techniques have emerged as viable tools for wavefront metrology and sample imaging applications. These methods are based on the measurement of near-field images. Thanks to their ...

    • The PERCIVAL detector: first user experiments 

      Correa, J.; Mehrjoo, M.; Battistelli, R.; Lehmkühler, F.; Marras, A.; Wunderer, C. B.; Hirono, T.; Felk, V.; Krivan, F.; Lange, S.; Shevyakov, I.; Vardanyan, V.; Zimmer, M.; Hoesch, M.; Bagschik, K.; Guerrini, N.; Marsh, B.; Sedgwick, I.; Cautero, G.; Stebel, L.; Giuressi, D.; Menk, R. H.; Greer, A.; Nicholls, T.; Nichols, W.; Pedersen, U.; Shikhaliev, P.; Tartoni, N.; Hyun, H. J.; Kim, S. H.; Park, S. Y.; Kim, K. S.; Orsini, F.; Iguaz, F. J.; Büttner, F.; Pfau, B.ORCIDiD; Plönjes, E.; Kharitonov, K.; Ruiz-Lopez, M.; Pan, R.; Gang, S.; Keitel, B.; Graafsma, H. (Journal of Synchrotron Radiation, 2022-11-25)
      The PERCIVAL detector is a CMOS imager designed for the soft X‐ray regime at photon sources. Although still in its final development phase, it has recently seen its first user experiments: ptychography at a free‐electron ...

    • Tomographic reconstruction with a generative adversarial network 

      Yang, Xiaogang; Kahnt, Maik; Brückner, Dennis; Schropp, Andreas; Fam, Yakub; Becher, Johannes; Grunwaldt, Jan-Dierk; Sheppard, Thomas L.; Schroer, Christian G. (Journal of Synchrotron Radiation, 2020)
      This paper presents a deep learning algorithm for tomographic reconstruction (GANrec). The algorithm uses a generative adversarial network (GAN) to solve the inverse of the Radon transform directly. It works for independent ...
