Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

Fourier transform holography at the wavelength limit

, 2022
Paper DTh2E.4We present a table-top Fourier transform holography experiment that achieved a record-high resolution of 34 nm. By employing phase retrieval techniques, the resolution was improved to 23 nm (

Profiling Co‐Occurrent Morphological Phenotypes and Their Degree of Expression Severity in Vacuolated Cells by Holo‐Tomographic Flow Cytometry and Fractal Analysis

Advanced Intelligent Systems, EarlyView.
HTFC gets 3D refractive index tomograms of flowing cells. Label‐free monocytes are engineered to express patterns of cytoplasmic vacuoles. From the tomogram, an efficient dimensionality reduction is operated. Interpretable features are extracted to classify the expression severity of phenotypes coexisting in each cell, visually represented by a seven ...

Identification and Size Estimation of Non-Spherical Nanoparticles using Polarization-Resolved Holography

, 2020
Dual-view polarization-resolved digital holography is used to record the polarization response of the scattered light from both spherical and non-spherical nanoparticles. A model based on the T-matrix method is developed to map the polarization to a size

Autofocusing of optical scanning holography based on entropy minimization [PDF]

, 2015
In optical scanning holography, extracting distance of object is an indispensable step for numerical reconstruction. In this paper, we use entropy as a measurement to achieve autofocusing under different situations.

Portable Filter-Free Lens-Free Incoherent Digital Holography System

Photonics
A portable incoherent digital holography system without a polarization filter or a refractive lens was developed. Phase-shifted self-interference incoherent holograms of light diffracted from an object were generated without attenuation due to a ...

Bayesian Optimization of Grayscale Patterns for Layer‐Height Accuracy in Projection Multi‐Photon 3D Printing

Laser &Photonics Reviews, EarlyView.
Bayesian optimization combined with in situ quantitative phase imaging enables autonomous correction of layer‐height deviations in projection multi‐photon lithography. By jointly tuning model parameters and grayscale exposure settings, the method achieves more uniform and accurate layers within 300 prints, offering a fast, data‐efficient route to ...
