Very high resolution X-ray imaging has been the subject of considerable research over the
past few decades. However, the spatial resolution of these methods is limited by the …

X-ray sources are develo** rapidly and their coherent output is growing correspondingly.
The increased coherent flux from modern X-ray sources is being matched with an …

X-ray diffraction microscopy (XDM) is a new form of X-ray imaging that is being practiced at
several third-generation synchrotron-radiation X-ray facilities. Nine years have elapsed …

We present the first single-shot images of ferromagnetic, nanoscale spin order taken with
femtosecond x-ray pulses. X-ray-induced electron and spin dynamics can be outrun with …

Abstract The Linac Coherent Light Source (LCLS) became the first ever operational hard x-
ray free-electron laser in 2009. It will operate as a user facility capable of delivering unique …

Advances in the development of free-electron lasers offer the realistic prospect of nanoscale
imaging on the timescale of atomic motions. We identify X-ray Fourier-transform holography …

Fourier transform holography (FTH) is a lensless imaging technique where the wave
scattered by an object is superimposed with the wave scattered by a reference source …

Ultrafast X-ray imaging on individual fragile specimens such as aerosols, metastable
particles, superfluid quantum systems and live biospecimens provides high-resolution …

We introduce a generalization of Fourier transform holography that allows the use of the
boundary waves of an extended object to act as a holographic-like reference. By applying a …

We demonstrate coherent diffraction imaging using multiple harmonics from a high-
harmonic generation source. An algorithm is presented that builds the known incident …
