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 …

When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

For quantitative phase imaging (QPI) based on transport-of-intensity equation (TIE), partially
coherent illumination provides speckle-free imaging, compatibility with brightfield …

A cellular-level study of the pathophysiology is crucial for understanding the mechanisms
behind human diseases. Recent advances in quantitative phase imaging (QPI) techniques …

Illumination-based differential phase contrast (DPC) is a phase imaging method that uses a
pair of images with asymmetric illumination patterns. Distinct from coherent techniques, DPC …

The well-known transport of intensity equation (TIE) allows the phase of a coherent field to
be retrieved non-interferometrically given positive defined intensity measurements and …

Computational microscopy, as a subfield of computational imaging, combines optical
manipulation and image algorithmic reconstruction to recover multi-dimensional microscopic …

计算光学成像是一种通过联合优化光学系统和信号处理以实现特定成像功能与特性的新兴研究
