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

We demonstrate a simple method for quantitative phase imaging of tiny transparent objects
such as living cells based on the transport of intensity equation. The experiments are …

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 …

In this paper, we demonstrate a cost effective set-up for transport of intensity equation (TIE)-
based single-shot phase imaging. A Michelson interferometer like set-up has been utilized …

The transport of intensity equation (TIE) allows to recover the phase of a microscopy sample
from differently focused intensity measures along the axial direction of its optical field. In the …

We present a cost-effective, simple, and robust method that enables single-shot quantitative
phase imaging (QPI) based on the transport of intensity equation (TIE) using an add-on …

Various quantitative phase imaging techniques exist capable of characterizing transparent
and low-contrast samples without the addition of dyes or fluorescent probes. Among them …

Holographic data storage (HDS), in which both the amplitude and the phase of a signal
beam are modulated, has been extensively studied with the goal of increasing its storage …

Phase recovery based on the transport of intensity equation (TIE) is a promising method for
quantitative phase imaging, which is useful for the observation of dynamic objects. This …

The transport of intensity equation (TIE) is the basis of a powerful non-interferometric
technique for phase retrieval. When intensity gradients are present, the generalized belief is …
