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 crystallography has been central to the development of many fields of science over the
past century. It has now matured to a point that as long as good-quality crystals are …

This paper develops a novel framework for phase retrieval, a problem which arises in X-ray
crystallography, diffraction imaging, astronomical imaging, and many other applications. Our …

We discuss unique features of lens-free computational imaging tools and report some of
their emerging results for wide-field on-chip microscopy, such as the achievement of a …

Phase retrieval, ie the problem of recovering a function from the squared magnitude of its
Fourier transform, arises in many applications, such as X-ray crystallography, diffraction …

Key insights into the behavior of materials can be gained by observing their structure as they
undergo lattice distortion. Laser pulses on the femtosecond time scale can be used to …

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 …

Coherent diffraction imaging (CDI) is high-resolution lensless microscopy that has been
applied to image a wide range of specimens using synchrotron radiation, X-ray free-electron …

Lensfree in-line holographic microscopy offers sub-micron resolution over a large field-of-
view (eg,~ 24 mm^ 2) with a cost-effective and compact design suitable for field use …
