Imaging malaria parasites across scales and time

open access: yesJournal of Microscopy, EarlyView.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

Investigating tricalcium silicate dissolution kinetics in cementitious materials through single‐particle analysis

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 7, July 2025.
Abstract The dissolution kinetics of tricalcium silicate (Ca3SiO5, or C3S), the primary component of ordinary Portland cement, are critical to cement hydration, which governs key properties, such as setting, hardening, long‐term mechanical performance, and durability.

Single-exposure full-field multi-depth imaging using low-coherence holographic multiplexing

open access: yes, 2018
We present a new interferometric imaging approach that allows for multiple-depth imaging in a single acquisition, using off-axis low-coherence holographic multiplexing. This technique enables sectioned imaging of multiple slices within a thick sample, in

Single-shot common-path off-axis dual-wavelength digital holographic microscopy.

open access: yesApplied Optics, 2020
A single-shot common-path off-axis self-interference dual-wavelength digital holographic microscopic (DHM) system based on a cube beam splitter is demonstrated to expand the phase range in a stepped microstructure and for simultaneous measurement of the ...

Phase Retrieval for Digital Holographic Microscopy With Defocused Holograms

open access: yesIEEE Photonics Journal, 2018
A new phase retrieval technique in digital holographic microscopy (DHM) with three defocused holograms is proposed. Given the defocusing distance, the phase distributions of tested specimen can be reconstructed with a simple algebraic equation.

High‐Fidelity Computational Microscopy via Feature‐Domain Phase Retrieval

open access: yesAdvanced Science, Volume 12, Issue 21, June 5, 2025.
An innovative phase retrieval framework, termed FD‐PR, is uniquely established in the image's feature domain through the feature‐extracted, physical‐driven regression with interfaces for combining physics and image processing constraints. FD‐PR takes advantage of invariance components of an image against presences of model mismatch and uncertainty ...

Digital Holographic Microscopy and Python

open access: yes, 2019
Holograms are Interference, circular pattern of bright and dark lines surrounding an object due to light passage over it in 2D plane. The Hungarian-British physicist Dennis Gabor was awarded with Nobel Prize for inventing and applying this phenomenon for improving electron microscopy in 1971.

Single-shot incoherent color digital holographic microscopy system with static polarization-sensitive optical elements

open access: yesJournal of Optics, 2020
We propose a digital holographic microscope for the single-shot multicolor three-dimensional (3D) image sensing of specimens illuminated by spatially and temporally incoherent white light.

Special Issue on Digital Holographic 3D Imaging: Capture, Display, and Evaluation

open access: yesETRI Journal, 2019
Holography has been fascinating people for almost 70 years (since Gabor's invention in 1947) as a true three‐dimensional (3D) imaging technology that can replicate 3D scenes in free space.
