The finite-difference time-domain (FDTD) method is a widespread numerical tool for full-
wave analysis of electromagnetic fields in complex media and for detailed geometries …

Abstract Mobile health, or 'mHealth', is the application of mobile devices, their components
and related technologies to healthcare. It is already improving patients' access to treatment …

Quantitative phase imaging (QPI) has emerged as a valuable method for investigating cells
and tissues. QPI operates on unlabelled specimens and, as such, is complementary to …

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

Optical imaging of nanoscale objects, whether it is based on scattering or fluorescence, is a
challenging task due to reduced detection signal-to-noise ratio and contrast at …

We demonstrate a handheld on-chip biosensing technology that employs plasmonic
microarrays coupled with a lens-free computational imaging system towards multiplexed …

Optical compound microscope has been a major tool in biomedical imaging for centuries. Its
performance relies on relatively complicated, bulky and expensive lenses and alignment …

Wide field-of-view (FOV) and high-resolution imaging requires microscopy modalities to
have large space-bandwidth products. Lensfree on-chip microscopy decouples resolution …

Optical examination of microscale features in pathology slides is one of the gold standards
to diagnose disease. However, the use of conventional light microscopes is partially limited …

As a label‐free imaging technique, quantitative phase imaging (QPI) provides optical path
length information of transparent specimens for various applications in biology, materials …
