Quantitative phase imaging, integrated with artificial intelligence, allows for the rapid and
label-free investigation of the physiology and pathology of biological systems. This review …

Improving access to effective and affordable healthcare has long been a global endeavor. In
this quest, the development of cost-effective and easy-to-use medical testing equipment that …

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 …

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 …

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 …

We report a portable lensless on-chip microscope that can achieve< 1 µm resolution over a
wide field-of-view of∼ 24 mm2 without the use of any mechanical scanning. This compact …

We present a lens-free optical tomographic microscope, which enables imaging a large
volume of approximately 15 mm3 on a chip, with a spatial resolution of< 1 μm×< 1 μm×< 3 …

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 …

We report a field-portable lensfree microscope that can image dense and connected
specimens with sub-micron resolution over a large field-of-view of∼ 30 mm2 (ie,∼ 6.4 …

We present a detailed investigation of the performance of lens-free holographic microscopy
toward high-throughput on-chip blood analysis. Using a spatially incoherent source that is …
