Digital holographic microscopy (DHM), which combines digital holography with optical
microscopy, is a wide field, minimally invasive quantitative phase microscopy (QPM) …

Gallium nitride (GaN) light-emitting-diode (LED) technology has been the revolution in
modern lighting. In the last decade, a huge global market of efficient, long-lasting, and …

High-resolution optical microscopy has traditionally relied on high-magnification and high–
numerical aperture objective lenses. In contrast, lensless microscopy can provide high …

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 …

Microscopy is one of the main research and application areas of digital holography. Direct
access to the phase as well as amplitude profiles makes quantitative phase microscopy by …

Particle tracking is a fundamental technique for investigating a variety of biophysical
processes, from intracellular dynamics to the characterization of cell motility and migration …

We demonstrate lensfree holographic microscopy on a chip to achieve~ 0.6 µm spatial
resolution corresponding to a numerical aperture of~ 0.5 over a large field-of-view of~ 24 …

Despite the rapid progress in optical imaging, most of the advanced microscopy modalities
still require complex and costly set-ups that unfortunately limit their use beyond well …

We demonstrate lensfree digital microscopy on a cellphone. This compact and light-weight
holographic microscope installed on a cellphone does not utilize any lenses, lasers or other …

Better understanding of particle-particle and particle-fluid interactions requires accurate 3D
measurements of particle distributions and motions. We introduce the application of in-line …
