Color Images from the Shadow of a Sample
The new approach allows an image of a large area to be produced from a single exposure, without the need for focusing and scanning.

Scientists at Germany's University of Göttingen generated X-ray images in color from a single exposure.
The researchers employed a color X-ray camera developed by German detector technology developer PNSensor, as well as a novel imaging system comprised of a gold-coated plate positioned between the object and the detector.
Swiss nanostructure startup XRNanotech fabricated lenses for the camera to the researchers' specifications.
The sample casts a shadow, whose detected intensity pattern yields data about the distribution of fluorescing atoms in the sample for decoding by a computer algorithm.
Göttingen's Jakob Soltau said the algorithm "allows us to quickly and robustly create a sharp image, simultaneously for each X-ray color."
