Using an inexpensive module for Quantitative Phase Imaging [PDF]
EPJ Web of Conferences, 2023 We report on modular implementation of digital holography that we recently proposed. The module is designed such that it may be added to an existing brightfield microscope’s image port for digital holographic microscopy functionality. The proposed system

Variational Hilbert Quantitative Phase Imaging [PDF]
Scientific Reports, 2020 AbstractUtilizing the refractive index as the endogenous contrast agent to noninvasively study transparent cells is a working principle of emerging quantitative phase imaging (QPI). In this contribution, we propose the Variational Hilbert Quantitative Phase Imaging (VHQPI)—end-to-end purely computational add-on module able to improve performance of a ...

Quantitative Phase and Absorption Contrast Imaging
IEEE Transactions on Computational Imaging, 2022 We present an algorithm for coherent diffractive imaging with phaseless measurements. It treats the forward model as a combination of coherent and incoherent waves. The algorithm reconstructs absorption and phase contrast that quantifies the attenuation and the refraction of the waves propagating through an object.

Quantitative phase imaging of arthropods [PDF]
Journal of Biomedical Optics, 2015 Classification of arthropods is performed by characterization of fine features such as setae and cuticles. An unstained whole arthropod specimen mounted on a slide can be preserved for many decades, but is difficult to study since current methods require sample manipulation or tedious image processing.

Quantitative Phase Imaging Using Deep Learning-Based Holographic Microscope
Frontiers in Physics, 2021 Digital holographic microscopy enables the measurement of the quantitative light field information and the visualization of transparent specimens. It can be implemented for complex amplitude imaging and thus for the investigation of biological samples ...

Quantitative Phase Imaging of Thin Film Surface
Acta Physica Polonica A, 2021 In this study, the white light diffraction phase microscopy and the generalized Morse wavelet are proposed to achieve practical and precise measurement of a thin film surface. The white light diffraction phase microscopy provides low speckle noise and single-shot measurement, and thus it has been used to produce an image with interference fringes from ...

Virtual optofluidic time-stretch quantitative phase imaging
APL Photonics, 2020 Optofluidic time-stretch quantitative phase imaging (OTS-QPI) is a potent tool for biomedical applications as it enables high-throughput QPI of numerous cells for large-scale single-cell analysis in a label-free manner.
