Massively Parallel X-Ray Holography

Posted by Soulskill on from the thank-you-for-not-inventing-a-witty-acronym dept.

Roland Piquepaille writes "An international group of scientists has produced some of the sharpest x-ray holograms of microscopic objects ever made. According to one of them, they improved the efficiency of holography by a factor of 2,500. In order to achieve these spectacular results, they put a uniformly redundant array next to the object to image. And they found that this parallel approach multiplied 'the efficiency of X-ray Fourier transform holography by more than three orders of magnitude, approaching that of a perfect lens.' Besides these impressive achievements, it's worth noting that this technology has been inspired by the pinhole camera, a technique used by ancient Greeks. '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.'"

    HushEncryptionEngine.jar which is the same as on the web site is located in /applets/ foler in .zip file

    This part is obvious FUD

    You might argue that 5 hours isn't much
