The problem of phase retrieval, ie, the recovery of a function given the magnitude of its
Fourier transform, arises in various fields of science and engineering, including electron …

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

Iterative projection algorithms are successfully being used as a substitute of lenses to
recombine, numerically rather than optically, light scattered by illuminated objects. Images …

We propose and experimentally demonstrate a simple and robust approach for retrieving
arbitrary complex-valued fields from three or more diffraction intensity recordings. We need …

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 …

The modern electron microscope, as a result of recent revolutionary developments and
many evolutionary ones, now yields a wealth of quantitative knowledge pertaining to …

Microscopy has greatly advanced our understanding of biology. Although significant
progress has recently been made in optical microscopy to break the diffraction-limit barrier …

We have developed an algorithm that combines the concept of optimization with the
conventional hybrid input-output (HIO) algorithm for phase retrieval of oversampled …

Tomography has made a revolutionary impact on the physical, biological and medical
sciences. The mathematical foundation of tomography is to reconstruct a three-dimensional …

Developments in the fields of lab-on-a-chip and microfluidic technology have benefited
nanomaterial production processes due to fluid miniaturization. The ability to acquire …
