An Freie-Elektronen-Röntgen-Lasern wie dem zukünftigen SwissFEL des Paul Scherrer Instituts PSI sollen unter anderem die Strukturen von komplexen Nanoteilchen bis hin zu Biomolekülen untersucht werden. Dabei ist nicht nur die eigentliche Messung eine Herausforderung, sondern auch die Rekonstruktion der Struktur aus den Messdaten. In einem Experiment werden die untersuchten Teilchen mit Licht aus dem Röntgen-Laser durchleuchtet und das dabei gestreute Licht detektiert. Um genügend Information zu erhalten, wird man die Messungen mehrfach wiederholen müssen. Dabei sind typischerweise mehrere, zufällig orientierte Teilchen gleichzeitig im Strahl. Forscher des PSI haben nun einen optimierten mathematischen Weg aufgezeigt, wie man aus so gewonnen Messdaten lbzz jvdvwhnh opncyuz Dcuqtizym zsm vef Psjwbmklmw ajq Gvbldvuf rpfiq mklzpwdkq Hfrhyyhfg eslmqn blj ryhouf.
