The Brightest, Sharpest, Fastest X-Ray Holograms Yet

An international group of scientists has produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made, thousands of times more efficiently than previous x-ray-holographic methods.

The two experiments demonstrate that massively parallel holographic x-ray images with nanometer-scale resolution can be made of objects measured in microns, in times as brief as femtoseconds, using a pinhole array.

By knowing the precise layout of a pinhole array, including the different sizes of the different pinholes, a computer can recover a bright, high-resolution image numerically.

The researchers believe the holograms could be pushed to only a few nanometers, or, using computer refinement, even better.
