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

ETRI 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.

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

Journal 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.

The Comparison of the Efficacy and Safety of Fractional 1064 nm Nd:YAG Picosecond Laser and Fractional Q‐Switched 1064‐nm Nd:YAG Laser in the Improvement of Photoaging: A Split‐Face Study

Journal of Cosmetic Dermatology, Volume 24, Issue 7, July 2025.
ABSTRACT Background Facial photoaging is a complex biological process influenced by both internal and external factors. It is characterized by wrinkles, enlarged pores, and rough skin. Despite various clinical treatments, they often have limited effectiveness, significant side effects, and extended recovery times. There is a need for more effective and

Single-shot digital holographic microscopy based on computational telecentricity using a single-arm off-axis interferometer

ICT Express, 2018
We propose a single-shot digital holographic microscopy based on computational telecentricity with a single-arm off-axis interferometer (SA-OAI), which is composed of optical recording, computational compensation and retrieving processes.

Polyalanine Expansion in PABPN1 Alters the Structure and Dynamics of Its Nuclear Aggregates in Differentiated Muscle Cells

The FASEB Journal, Volume 39, Issue 12, 30 June 2025.
The accumulation of aggregation‐prone proteins is a hallmark of aging cells. Pathogenic forms of these aggregates are associated with neurodegenerative, neuromuscular, and muscular diseases, yet the differences between pathogenic and non‐pathogenic aggregates remain unclear.

Simultaneous three-wavelength unwrapping using external digital holographic multiplexing module

, 2018
We present an external interferometric setup that is able to simultaneously acquire three wavelengths of the same sample instance without scanning or multiple exposures. This setup projects onto the monochrome digital camera three off-axis holograms with

Automatic cross filtering for off-axis digital holographic microscopy

Results in Physics, 2020
Off-axis digital holographic microscopy (DHM) is a significant quantitative phase imaging (QPI) modality in a single shot. However, the reconstructed quality of the image in the off-axis DHM is governed by the spatial filtering in the spectral domain of ...

Comparative analysis of digital holographic microscopy and digital lensless holographic microscopy for quantitative phase imaging

Optics Continuum
This study provides a detailed comparison of two widely used quantitative phase imaging (QPI) techniques: single-shot off-axis digital holographic microscopy (DHM) and digital lensless holographic microscopy (DLHM). The primary aim is to evaluate and contrast critical aspects of their imaging performance, including spatial phase sensitivity, phase ...

Microsphere-assisted quantitative phase microscopy: a review

Light: Advanced Manufacturing
Light microscopes are the most widely used devices in life and material sciences that allow the study of the interaction of light with matter at a resolution better than that of the naked eye. Conventional microscopes translate the spatial differences in

Label-free spatio-temporal monitoring of cytosolic mass, osmolarity, and volume in living cells

Nature Communications, 2019
Label-free, spatio-temporal imaging of cellular physiological responses is challenging. Here the authors combine digital holographic microscopy with a millifluidic chip and mathematical modelling to quantify cell volume, mass and cell uptake under ...
