Quantitative phase imaging (QPI) of transparent samples plays an essential role in multiple
biomedical applications, and miniaturizing these systems will enable their adoption into …

Phase retrieval is a noninterferometric quantitative phase imaging technique that has
become an essential tool in optical metrology and label-free microscopy. Phase retrieval …

Differential interference contrast (DIC) microscopy provides the ability to visualize
transparent phase samples such as living cells and tissues, which plays an essential role in …

Spiral phase contrast imaging and bright-field imaging are two widely used modes in
microscopy, providing distinct morphological information about objects. However …

As the two most representative operation modes in an optical imaging system, bright-field
imaging and phase contrast imaging can extract different morphological information on an …

Quantitative phase microscopy (QPM), a technique combining phase imaging and
microscopy, enables visualization of the 3D topography in reflective samples, as well as the …

Edge enhancement and polarization detection are critical to image transparent or low-
contrast samples. However, currently available systems are limited to performing only a …

Differential phase contrast microscopy (DPC) provides high-resolution quantitative phase
distribution of thin transparent samples under multi-axis asymmetric illuminations. Typically …

We present a single-shot isotropic quantitative phase imaging method based on color-
multiplexed differential phase contrast. In our method, the illumination source is modulated …

We propose a lensfree on-chip microscopy approach for wide-field quantitative phase
imaging (QPI) based on wavelength scanning. Unlike previous methods, we found that a …
