Ankylography: Three-dimensional Structure Determination from a Single View

The ability to determine the structure of matter in three dimensions has profoundly advanced our understanding of nature. Traditionally, the most widely used schemes for 3D structure determination of an object are implemented by acquiring multiple measurements over various sample orientations, as in the case of crystallography and tomography, or by scanning a series of thin sections through the sample, as in confocal microscopy. Now, the Miao group, in collaboration with Richard Sandberg and Henry Kapteyn of University of Colorado, Boulder and Jincheng Du of University of North Texas, has developed a novel 3D imaging modality, termed ankylography (derived from the Greek words ankylos meaning ‘curved’ and graphein meaning ‘writing’), which under certain circumstances enables complete 3D structure determination from a single exposure using a monochromatic incident beam. With further development, this approach of obtaining complete 3D structure information from a single view could find broad applications in the physical and life sciences. For more details, please refer to the paper, which is published in Nature.

UCLA researchers, Kevin Raines, Sara Salha, Huaidong Jiang, Jose Rodríguez and John Miao have played an important role in developing this method. This work is also in collaboration with Richard Sandberg and Henry Kapteyn of University of Colorado, Boulder and Jincheng Du of University of North Texas.
