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 …

The phase information of a complex field is routinely obtained using coherent measurement
techniques as, eg, interferometry or holography. The obtained measurement result is subject …

Three-dimensional (3D) imaging has attracted more and more interest because of its
widespread applications, especially in information and life science. These techniques can …

摘要相位恢复与定量相位成像是光学测量与成像技术领域的一个重要课题. 传统干涉测量法依赖
高度相干光源的干涉叠加, 干涉装置复杂, 测量环境要求苛刻, 引入的散斑噪声极大地限制了传统 …

Optimization-based phase retrieval method for digital lensless holographic microscopy in
the double-plane recording configuration is proposed. In our method the phase retrieval is …

We report variable shear interferometers employing liquid-crystal-based geometric-phase
(GP) gratings. Conventional grating-based shear interferometers require two lateral shifts of …

The transport-of-intensity equation (TIE) is a well-established non-interferometric phase
retrieval approach, which enables quantitative phase imaging (QPI) of transparent sample …

We present a novel, accurate, full-filed, dynamic quantitative phase imaging (QPI) technique
by using multi-wavelength multiplexing and multi-plane iterative phase retrieval algorithm. In …

Structured light illumination is a well-established technology for noncontact 3D surface
measurements. A common challenge in those systems is to obtain the absolute surface …
