Convergent-Beam X-ray Crystallography
Chufeng Li, Margarita Zakharova, Mauro Prasciolu +19
Molecular and polymeric crystals show a wide range of functional properties that arise from the interplay between the atomic-scale structure of their constituent molecules and the…
Convergent-beam attosecond X-ray crystallography
Henry N. Chapman, Chufeng Li, Saša Bajt +17
Sub-angstrom spatial resolution of electron density coupled with sub-femtosecond temporal resolution is required to directly observe the dynamics of the electronic structure of a m…
3D Reconstruction of unstained cells from a single defocused hologram
Sunaina Rajora, Mansi Butola, Kedar Khare
We investigate the problem of 3D complex field reconstruction corresponding to unstained red blood cells (RBCs) with a single defocused off-axis digital hologram. We employ recentl…
Robust phase retrieval with complexity-guidance for coherent X-ray imaging
Mansi Butola, Sunaina Rajora, Kedar Khare
Reconstruction of a stable and reliable solution from noisy incomplete Fourier intensity data recorded in a coherent X-ray imaging (CXI) experiment is a challenging problem. The Re…
True 3D reconstruction in digital holography
Jasleen Birdi, Sunaina, Mansi Butola +1
We examine the nature of the 3D image as obtained by replay (or back-propagation) of the object wave from the hologram recording plane to the original object volume. While recordin…
Mean Gradient Descent: An optimization approach for single-shot interferogram analysis
Sunaina, Mansi Butola, Kedar Khare
Complex object wave recovery from single-shot interference pattern is an important practical problem in interferometry and digital holography. The most popular single-shot interfer…
Phase retrieval with complexity guidance
Mansi Butola, Sunaina, Kedar Khare
Iterative phase retrieval methods based on the Gerchberg-Saxton (GS) or Fienup algorithm require a large number of iterations to converge to a meaningful solution. For complex-valu…
