London, August 2 : An international team of U. S. and German researchers has produced two of the brightest and sharpest x-ray holograms of microscopic objects ever made, with the help of an approach they claim is thousands of times more efficient than previous x-ray-holographic methods.
This advancement is a result of the efforts of experts associated with the Advanced Light Source (ALS) at the U. S. Department of Energy’s Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg.
The researchers have revealed that their approach is inspired by the pinhole camera, a technique known since ancient times.
