Quantitative phase imaging (QPI) is a label-free, wide-field microscopy approach with
significant opportunities for biomedical applications. QPI uses the natural phase shift of light …

Over the past decade, the use of probiotics to modify the gut microbiome has become a
public spotlight in reducing the severity of a number of chronic diseases such as …

Empowered by pixel super-resolution (PSR) and phase retrieval techniques, lensless on-
chip microscopy opens up new possibilities for high-throughput biomedical imaging …

We propose a novel approach for lensless single-shot phase retrieval, which provides pixel
super-resolution phase imaging. The approach is based on a computational separation of …

Quantitative phase imaging (QPI) techniques are widely used for the label-free examining of
transparent biological samples. QPI techniques can be broadly classified into interference …

In this paper, an iterative denoising phase retrieval method is proposed to solve the twin-
image problem in continuous-wave terahertz in-line digital holography. The iterative …

Lensless imaging with a mask is an attractive topic as it enables a compact configuration to
acquire wavefront information of a sample with computational approaches. Most existing …

Multiple-plane phase retrieval method can recover the complete complex amplitude of the
optical field by recording a series of axial diffraction patterns at different distances. However …

A novel single camera combined with Risley prisms is proposed to achieve a super-
resolution (SR) imaging and field-of-view extension (FOV) imaging method. We develop a …

We report a new computational imaging methodology for complex optical field based on a
single-frame diffraction intensity pattern acquisition with a simplified aperture and an …
