Imaging with coherent X-rays

Abstract
There has been considerable interest over the last decade in the development of coherence imaging methods. Major goals of this research program are the development of molecular imaging methods suitable for use with the X-ray free electron lasers (XFEL) now operating at both SLAC in the USA and SPring8 in Japan, and high-resolution X-ray imaging with synchrotron and other short-wavelength sources. In this talk I will present the work of my group in Australia on the development of novel approaches to coherent imaging. We have paid a particular emphasis on imaging non-XFEL sources and on the measurement and inclusion of the coherence properties of the sources [1]. We have also begun exploring the development of novel highly coherent electron sources [2] which we believe promise to be an exciting emerging direction for very high-resolution coherent imaging. 1.
