Ab Initio Spatial Phase Retrieval via Intensity Triple Correlations
Nolan Peard, Kartik Ayyer, Henry N. Chapman
Second-order intensity correlations from incoherent emitters can reveal the Fourier transform modulus of their spatial distribution, but retrieving the phase to enable completely g…
Optical funnel to guide and focus virus particles for X-ray laser imaging
Salah Awel, Sebastian Lavin-Varela, Nils Roth +5
The need for precise manipulation of nanoparticles in gaseous or near-vacuum environments is encountered in many studies that include aerosol morphology, nanodroplet physics, nanos…
Photon statistics and signal to noise ratio for incoherent diffraction imaging
Fabian Trost, Kartik Ayyer, Henry Chapman
Intensity interferometry is a well known method in astronomy. Recently, a related method called incoherent diffractive imaging (IDI) was proposed to apply intensity correlations of…
Ptychographic X-ray Speckle Tracking with Multi Layer Laue Lens Systems
Andrew James Morgan, Kevin T. Murray, Mauro Prasciolu +19
The ever-increasing brightness of synchrotron radiation sources demands improved x-ray optics to utilise their capability for imaging and probing biological cells, nano-devices, an…
Ptychographic X-ray Speckle Tracking
Andrew J. Morgan, Harry M. Quiney, Saša Bajt +1
We present a method for the measurement of the phase gradient of a wavefront by tracking the relative motion of speckles in projection holograms as a sample is scanned across the w…
Hard X-ray multi-projection imaging for single-shot approaches
P. Villanueva-Perez, B. Pedrini, R. Mokso +7
Obtaining 3D information from a single X-ray exposure at high-brilliance sources, such as X-ray free-electron lasers (XFELs) [1] or diffraction-limited storage rings [2], allows th…
