This illustration shows the experimental design of the simulated 3-D X-ray imaging experiment performed by scientists at Argonne, Northwestern and Cornell. The X-ray beam passes through a nanofocusing optic at left, penetrates the sample at center, then proceeds to the detector at right. The simulation is helping scientists solve a nagging problem in optical science: how to prevent depth-of-focus loss with increased 3-D X-ray imaging resolution.
