AI Article Synopsis
- Lensless x-ray microscopy relies on recovering the phase of scattered radiation from a specimen, which is crucial for creating images.
- Researchers introduced a new phase retrieval method by encasing objects in superfluid helium nanodroplets, which supports the specimen and aids in image reconstruction.
- The technique is effective and produces detailed images, as demonstrated with xenon clusters showing transient quantum vortices within the delicate helium droplets.
Article Abstract
Lensless x-ray microscopy requires the recovery of the phase of the radiation scattered from a specimen. Here, we demonstrate a de novo phase retrieval technique by encapsulating an object in a superfluid helium nanodroplet, which provides both a physical support and an approximate scattering phase for the iterative image reconstruction. The technique is robust, fast-converging, and yields the complex density of the immersed object. Images of xenon clusters embedded in superfluid helium droplets reveal transient configurations of quantum vortices in this fragile system.
