Hologram System (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption A coherent X-ray beam illuminates both the sample and a uniformly redundant array placed next to it. The CCD detector (whose center is shielded from the direct beam) collects diffracted X-rays from both sample and URA. Processing the resulting interference patterns subsequently yields a hologram.
