Statistics In Diffractive Imaging
… describes reconstruction techniques in diffractive imaging when the data is exceptionally noisy and when crucial experimental parameters are unmeasured. In particular, this work focuses on two applications of diffractive imaging, single particle imaging with unoriented data and ultrafast …

Microscopy of Gold Microcrystals by Coherent X -Ray Diffractive Imaging
"The small wavelength and penetrating nature of X-ray radiation has long been used to solve the structure of materials. Inherent in these measurements is the loss of phase information in the intensity measurement; the so-called ""phase problem."" Third generation synchrotrons provide X-ray beams …

Coherent X -Ray Diffractive Imaging and Nucleation of Protein Crystals
The determination of the atomic structure of proteins is very important since much understanding of biological processes cannot be achieved without knowledge of the atomic structure. The preparation of high quality protein crystals suitable for structure determination often proves difficult and …

INVESTIGATION OF ADVANCED IMAGE RECONSTRUCTION ALGORITHMS FOR ELECTRON MICROSCOPY
… microscopy and introduces some basic concepts in imaging science. Chapter 2 takes a more in-depth discussion of elastic scattering in STEM and how beam propagation can be described analytically and computationally. The next two chapters focus on electron tomography, a technique that reconstructs …

Table-top XUV nanoscope
… (XUV) nanoscope suitable for coherent diffractive imaging (CDI). Intense spatially coherent ultrashort XUV and X-ray pulses are desired for nanoscale biological and material imaging. Such radiation can be produced via high harmonic generation (HHG) by focusing a highly intense …

Atomic structures of carbon nanomaterials studied by coherent electron diffraction
… method was studied by electron diffraction, imaging and spectroscopy. The results show that the detonation nanodiamonds have a majority of cubic diamond core smaller than the particle size. In addition, sub-ångström resolution of an individual nanodiamond was achieved bydiffractive imaging. …

Computational imaging and inverse techniques for high-resolution and instantaneous spectral imaging
… thesis, we develop a class of novel spectral imaging techniques that enable capabilities beyond the reach of conventional methods. Each development is based on computational imaging, which involves distributing the spectral imaging task between a physical and a computational system and then …
