New compact hyperspectral system captures 5-D images

Researchers have developed a compact imaging system that can measure the shape and light-reflection properties of objects with high speed and accuracy. This 5D hyperspectral imaging system—so-called because it captures ...

First published results from new X-ray laser

With the publication of the first experimental measurements performed at the facility, the European X-ray Free-Electron Laser (EuXFEL) has passed another critical milestone since its launch in September 2017. It is the first ...

Novel X-ray optics boost imaging capabilities at NSLS-II

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a new approach to 3-D x-ray imaging that can visualize bulky materials in great detail—an impossible task with conventional ...
