Coherent diffractive imaging (CDI) at X-ray free-electron lasers allows for resolving the structure [1] and light-induced dynamics [2] in individual nanostructures. We developed an experimental setup saving two consecutive images on spatially separated detectors, allowing to follow the evolution of the same individual, non-reproducible particle after irradiation with an intense FEL pulse. In this context, we also developed and commissioned a multilayer-mirror-based split-and-delay unit (SDU) at FLASH delivering XUV-double pulses up to 650 ps delay [3]. The concepts of the imaging setup and the SDU will be introduced and proof-of-principle results will be presented.
