15. Exploring the Limits of Coherent Diffractive Imaging

Henry Chapman (CFEL DESY)

5/20/26, 9:15 AM

Invited talk

If the amplitude and phase of a coherently scattered monochromatic wave can be measured or determined, then that wave can be numerically propagated backwards in time to form a map of the interaction of the wave with an object (i.e. an image). The phase of the wave can often be inferred from a measurement of the intensity pattern alone. This is particularly useful for imaging with X-rays, where...

22. Broadband ptychography for soft X-ray imaging with a high-order harmonic source

Wilhelm Eschen (CU Boulder, JILA)

5/20/26, 9:50 AM

Invited talk

Recent advances in ultrafast laser technology have facilitated the development of high-brightness, high-order harmonic generation (HHG) sources. These compact tabletop systems now enable high-resolution coherent diffractive imaging (CDI) experiments previously restricted to large-scale facilities [1, 2]. To date, HHG-based imaging has been largely confined to the EUV spectral range (<100 eV),...

24. Using the longitudinal coherence of a seeded free electron laser to enable single-shot videography

Abraham Lewis Levitan (Paul Scherrer Institute)

5/20/26, 10:25 AM

Contributed talk

Stroboscopic imaging is a popular use of free electron lasers (FELs), enabling studies following the dynamics of a variety of systems ranging from fast-moving objects [1] to ultrafast magnetic dynamics [2]. However, these methods face a fundamental limitation: that each flash of light from the FEL produces a single image. Therefore, to stitch together a full movie of a time-dependent process,...
